A search-and-fill strategy to code generation for complex software requirements

Context:The realm of software development has seen significant transformations with the rise of Low-Code Development (LCD) and the integration of Artificial Intelligence (AI), particularly large language models, into coding practices. The proliferation of open-source software also offers vast resources for developers. Objective:We aim to combine the benefits of modifying retrieved code with the use of an extensive code repository to tackle the challenges of complex control structures and multifunctional requirements in software development. Method:Our study introduces a Search-and-Fill strategy that utilizes natural language processing (NLP) to dissect complex software requirements. It extracts control structures and identifies atomic function points. By leveraging large-scale pre-trained models, the strategy searches for these elements to fill in the automatically transformed program structures derived from descriptions of control structures. This process generates a code snippet that includes program control structures and the implementations of various function points, thereby facilitating both code reuse and efficient development. Results:We have validated the effectiveness of our strategy in generating code snippets. For natural language requirements involving multifunctional complex structures, we constructed two datasets: the Basic Complex Requirements Dataset (BCRD) and the Advanced Complex Requirements Dataset (ACRD). These datasets are based on natural language descriptions and Python code that were randomly extracted and combined. For the code snippets to be generated, we achieved the best results with the ACRD dataset, with BLEU-4 scores reaching up to 0.6326 and TEDS scores peaking at 0.7807. Conclusion:The Search-and-Fill strategy successfully generates a comprehensive code snippets, integrating essential control structures and functions to streamline the development process. Experimental results substantiate our strategy’s efficacy in optimizing code reuse by effectively integrating preprocessing and selection optimization approach. Future research will focus on enhancing the recognition of complex software requirements and further refining the code snippets.

On the formation and properties of amorphous and crystalline Li3-yBay/2OCl electrolytes

All-solid-state batteries (ASSBs) have potential to provide higher specific energy, higher power, and longer cycle life than Li-ion batteries (LIBs) for continuously increasing demands of high-performance rechargeable batteries with intrinsic safety. However, one of the barriers for successful design and fabrication of ASSBs is the lack of solid-state electrolytes (SSEs) that can meet multi-functional requirements for ASSBs. To address this issue, the present study investigates hydrothermal synthesis of amorphous and crystalline Ba-doped Li3OCl solid electrolytes and develops the understanding of the relationships between the synthesis conditions and electrochemical properties of the products. It is shown that the formation of an amorphous/crystalline Ba-doped Li3OCl mixture with little hydroxide impurities depends strongly on the hydrothermal reaction temperature, drying temperature, Ba concentration, and rate of removing OH− and H+ ions as steam from water solvated Ba-doped Li3OCl. The key to generate amorphous Li3OCl-based electrolytes with high ionic conductivities (7.65 × 10−3 S/cm) at room temperature is to create non-equilibrium synthesis conditions such as the one identified in this study. The understanding developed in this study will offer critical guidelines for synthesizing amorphous and crystalline Li3OCl-based electrolytes with superior electrochemical properties for ASSBs reliably and reproducibly in the near future.

Durable, multifunctional cotton fabrics with in situ deposited micro/nanomaterials for effective self–cleaning, oil–water separation and antibacterial activity

The facile modification of cotton fabrics for excellent self–cleaning, oil–water separation, and antibacterial activity is of great interest for multifunctional requirements. Herein, a durable, robust, fluorine–free multifunctional cotton fabric was fabricated via in-situ growing zeolitic imidazolate framework-67 (ZIF-67) on the cotton surface, followed by depositing hydrophobic SiO2 (H-SiO2) nanoparticles synthesized via an improved Stöber reaction. Meanwhile, the abundant hydroxyls of the cotton fabrics provided the necessary ion interaction sites for the uniform deposition of micro/nanomaterials, confirmed by the visualized Raman imaging technology. The resultant H-SiO2/ZIF-67@cotton fabric exhibited superhydrophobicity with a water contact angle of 159° and versatile self–cleaning, antifouling, oil–water separation, as well as prominent antibacterial activity against S. aureus and E. coli. At the same time, the superhydrophobic cotton fabric possessed excellent durability and stability against harsh environments, including abrasion, washing, acid, base, salt, and organic solvents. This facile technique can be applied for large-scale production of multifunctional superhydrophobic cotton fabrics due to its easy operation, low cost, and environmental friendliness.

Multifunctional and recyclable aerogel/fiber building insulation composites with sandwich structure

Fire, electromagnetic (EM) pollution, and sustainability require building insulation with fire resistance, EM interference shielding, and recyclability. However, fewer building insulation materials can fulfill these multifunctional requirements. Here, we report a multifunctional building thermal insulation material with a sandwich structure that uses SiO2 aerogel powder as the insulating filler phase, α-Al2O3 fiber as the refractory reinforcing phase, and carbon fiber mat (CFF) as the electromagnetic interference shielding layer prepared by the mixing-pressing-drying method. The effects of different SiO2 aerogel power contents on fire resistance, thermal insulation, and hydrophobicity, the effects of different carbon fiber contents on EMI performance, and the effects of CFF as an interlayer on compressive strength and recyclability were investigated. The results demonstrated exceptional fire resistance properties and low thermal conductivity (0.0529 W/m·K) with a SiO2 aerogel powder content of 11.2 wt%. Specifically, the structure of the aerogel/fiber composite remains intact and the temperature of the non-heated surface is lower than 75.8 ℃ after 4 min of continuous flame combustion. It can achieve a commercial shielding standard of 20 dB at a carbon fiber content of 5 wt%. In addition, CFF as interlayers can effectively improve the compression strength of the material and solve the problem of difficult recycling of carbon fiber. In conclusion, this sandwich structure of multifunctional aerogel/fiber composites provides new ideas for the manufacture of fire resistance, energy-saving, EM-protection, and recyclable building insulation materials.

A series of auxetic metamaterials with negative thermal expansion based on L-shaped microstructures

Mechanical metamaterials are facing various multi-functional requirements. In this study, a series of auxetic metamaterials with enhanced negative thermal expansion and improved stiffness are proposed. These metamaterials consist of four novel L-shaped microstructures connected in various clockwise or counterclockwise directions. Two length ratios and four angle parameters are utilized to define the geometry of these metamaterials. Both analytical analysis and validated numerical homogenization methods are employed to determine their effective thermoelastic properties, including effective Young's modulus, Poisson's ratio, and coefficient of thermal expansion. It is demonstrated that tailoring these microstructural geometries can modulate the effective thermoelastic properties of these metamaterials accordingly. By appropriately tailoring the geometric parameters, these metamaterials exhibit increased effective stiffness as well as more pronounced auxeticity and negative thermal expansion compared to traditional triangle and trapezoid microstructures. Notably, the in-plane effective anisotropic or isotropic Poisson's ratio and coefficient of thermal expansion can be adjustable over a broader range from negative to positive values. High stiffness, High strength, and near-zero thermal expansion can be achieved concurrently in these metamaterials, which is very conducive for structural designing in thermal environments. These metamaterials with a coupled design of stiffness, thermal expansion, and Poisson's ratio hold significant potential for advancing applications in satellite platforms, space structures, composite sandwiches, and precision equipment.

Self-assembled methodologies for the construction of DNA nanostructures and biological applications.

Over the past decades, deoxyribonucleic acid (DNA), as a versatile building block, has been widely employed to construct functionalized nanostructures. Among the diverse types of materials, DNA related nanostructures have gained growing attention due to their intrinsic programmability, favorable biocompatibility, and strong molecular recognition capability. The conventional construction strategy for building DNA structures is based on Watson-Crick base-pairing rules, which are mainly driven by the hydrogen bonding of bases. However, hydrogen bonding-based DNA nanostructures cannot meet the requirements of specific morphology and multifunctionality. Currently, various functional elements have been introduced to expand the synthetic methodologies for constructing the DNA hybrid nanostructures, including small molecules, peptide polymers, organic ligands and transition metal ions. Besides, the potential applications for these DNA hybrid nanostructures have also been explored. It has been demonstrated that DNA hybrid structures with various properties can be extensively applied in the fields of magnetic resonance, luminescence imaging, biomedical detection, and drug delivery systems. In this review, we highlight the pioneering contributions to the methodologies of DNA-based nanostructure assembly. Furthermore, the recent advances in drug delivery systems and biomedical diagnosis based on DNA hybrid nanostructures are briefly summarized.

A surface grafting strategy for antifouling/bioadhesive properties on a Janus-type polymeric thin film

There have been great technical challenges in preparation of a transparent polymeric thin film with Janus-type antifouling and bioadhesive properties on both surfaces, while maintaining the optical and mechanical characteristics of the bulk material. Herein, poly(2-hydroxyethyl methacrylate) (PHEMA), which is commonly used as an ophthalmic hydrogel, was employed as the bulk material for allowing consecutive surface grafting of functional polymer brushes, which eventually resulted in a Janus-type transparent thin film for potential biomedical implantation. First, a bromine-containing reagent served as the reactive initiator was silanized onto both surfaces of the PHEMA hydrogel thin film under a mild condition. Then, with the presence of selected physical shielding on one side using a scotch tape, polymer brushes with cell-adhesive Arg-Gly-Asp (RGD) peptide pendent groups were grafted from the other side of the PHEMA thin film, resulted in a highly improved cell attachment capability. Once the tape was removed and the RGD-modified surface was shielded, the zwitterionic polymer brushes comprising poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) segments were grafted on the surface, again through surface-initiated activators regenerated by electron transfer atom-transfer radical polymerization (SI-ARGET-ATRP). Hence, this side of the PHEMA film became super hydrophilic and exhibited antifouling properties on the surface. After the surface grafting modification, the whole PHEMA hydrogel maintained highly transparent and biocompatible for potential ophthalmic applications. This study provides a simple and rather universal strategy for fabricating Janus-type polymeric thin films with distinct biophysical/biochemical properties on both sides, which potentially applicable for the multifunctional requirements in biomedical applications.

Fracture behavior of ultra‐high performance lightweight concrete: In situ investigations using μ‐CT

AbstractIn various research projects at the University of Kassel, the concept of lightweight concrete has been combined with that of ultra‐high performance concrete (UHPC). Due to the high performance of the UHPC matrix, lightweight concretes (UHPLC) with strengths of 60‐130 MPa and bulk density of 1.5‐1.9 kg/m3 were developed. This material can be used in many applications because of its low thermal conductivity, low weight and thus easy to transport, recyclable and can be prefabricated. Thus, it meets today's multifunctional requirements for building materials. The brittle material failure of UHPC without fibers is not observed with UHPLC. Instead, the concretes fail in hourglass shape under compressive stress, as seen in standard concretes. This constellation is not only responsible for the reduction of strength and Y‐modulus, but also predicts a ductile failure. For a better interpretation of the fracture behavior and fracture pattern, images of the UHPLC were taken in a highresolution computed tomography (μ‐CT) scanner. Between images, the sample was loaded and the load was kept constant during the measurement. The data was evaluated on the basis of a damage parameter, as well as crack openings during stable crack growth and the crack pattern after the maximum load was exceeded.

Structural assessment of a multi-functional additively manufactured space component with bulk-lattice hybrid architecture

The paper shows the results of a research aimed to re-design a space component and to assess its structural integrity under the operating mechanical loading. To achieve multi-functional requirements, lattice structures were used in some regions of the component. An assessment procedure for static and random fatigue loads was developed. The procedure is applicable to components which have both bulk and lattice sections, and constitutes an important element for a successful diffusion of lattices. Experiments were performed on lattice samples and on breadboard samples, to validate the assumption of the assessment procedure. Good correlation was found between predictions and experiments.

Hybrid cross-linked sodium carboxymethyl starch/polyacrylamide flexible sensing hydrogels with adhesion, antimicrobial properties and multiple responses

Ionic hydrogels used as ideal and flexible strain sensor materials should have excellent mechanical, adhesive and antimicrobial properties. However, it is challenging to achieve these multifunctional requirements simultaneously. Herein, we designed and prepared a multifunctional ionic hydrogel with a multi-length tentacle bentonite backbone to initiate the free radical polymerization of acrylic acid bentonite (AABT) and acrylamide (AAm). The interactions of covalent cross-linking, hydrogen bonding cross-linking, charge interactions and physical entanglement between hybrid polyacrylamide-AABT (PAAm-AABT), sodium carboxymethyl starch (SCMS) and PAAm form an multi-in-one hybrid supramolecular network hydrogel (CABZ). This CABZ ion-conductive hydrogel is capable of detecting weak deformation with a detection limit of 1 % strain, high tensile properties of 995 %, excellent strength of 254.5 kPa, fast response (≈0.21 s), high sensitivity of 0.86 and high conductivity of 0.37 S/m. In addition, this CABZ ion-conductive hydrogel has impressive adhesion properties with shear adhesion strength up to 50.78 kPa and broad-spectrum antibacterial properties achieved by AABT-loaded ZnO nanoparticles. Through special AABT hybrid cross-linking, the CABZ ion-conductive hydrogel achieves stable mechanical properties, highly sensitive signal response and antimicrobial properties, which will make it a good choice for flexible wearable sensor materials.

Recent advances of carbon-based electromagnetic wave absorption materials facing the actual situations

In order to protect human safety, ensure the normal operation of precision instruments and improve national defense capabilities, it is necessary to develop electromagnetic waves absorbing materials to solve the issue of electromagnetic pollution. Carbon materials offer the characteristics of abundant species, low density, tunable conductivity, and outstanding mechanical property, enabling them to be used in a wide range of applications, and are of particular interest in the electromagnetic protection technology. In recent years, a large number of carbon-based absorbers have been synthesized and investigated in pursuit of the ideal goal with “thin thickness, light density, wide effective bandwidth and strong absorption” characteristics. In this review, it begins with a detailed description of the electromagnetic waves attenuation mechanisms. Next, a systematic summary of strategies to optimize the electromagnetic protection effect of carbon-based absorbers is provided. Thirdly, the multifunctional requirements of absorbing materials are discussed in depth when faced with practical application situations. Finally, we put forward the challenges and prospects of carbon-based protection materials, which can serve as a reference for the development of high-performance absorbers.

Nanosilk Template-Guided/Induced Construction of Brush-/Flower-like 3D Nanostructures.

Biomaterials with natural hierarchical structures typically exhibit extraordinary properties because of their multilevel structural designs. They offer many templates and models as well as inspiration for material design, particularly for fabricating structure-regulated, performance-enhanced, and function-enriched materials. Biopolymer-based nanocomposites with ingenious nanostructures constructed through ecofriendly and sustainable approaches are highly desirable to meet the multifunctional requirements of developing bioinspired materials. Herein, an all-silk fibroin-based nanocomposite with a brush-like nanostructure was constructed for the first time using a nanotemplate-guided assembly approach in which dissolved silk assembled directly on a silk nanowhisker (SNW) backbone to form peculiar nanobrushes based on the classical micelle model. Three-dimensional spider-like or centipede-like silk nanobrushes (SNBs) were fabricated by varying the SNW backbone length from 0.16 to 6 μm. The branches with average lengths of 32-290 nm were also adjustable. SNBs were further designed to regulate and induce biomineralization of hydroxyapatite (HAP) to form interesting flower-like nanostructures, in which the HAP nanosphere (diameters ∼16 nm) "core" was covered by SNBs with branches extending to form a "shell" (∼101 nm in length). Based on such protein nanotemplate-guided formation of nanoscale structures, practical hollow conduits with remarkable mechanical properties, biocompatibility, shape memory behavior, and bone engineering potential were fabricated. This study inspires the design of polymorphous biopolymer-based nanostructures with enhanced performance at multiple length scales where the weaknesses of individual building blocks are offset.

Experimental investigation of heat transfer and pressure losses across staggered Body Centered cubic arrays fabricated by Laser Powder Bed Fusion

Truss type lattice structures are regarded as a promising approach to design compact heat exchangers that are characterized also by good mechanical performances. The design of these structures can be tailored to satisfy multifunctional requirements and manufactured by exploiting the capabilities of additive manufacturing. This study reports on the experimental characterization of the aerothermal behaviour of new Body-Centred Cubic (BCC) lattice stagger arrays in a rectangular channel, which differ by the truss diameter. The heat exchangers are made from AlSi10Mg by means of Laser Powder Bed Fusion, and the geometric conformity and surface roughness of the internal features were characterized through optical and non-destructive methods to precisely define the boundary conditions at which the aero-thermal performances are provided. By so doing, some marginal defects caused by inherent limitations of the technology were observed, and relevant information in the perspective of designing new structures on a smaller characteristic scale were collected. The samples were then tested on a dedicated test rig by applying uniform heat flux boundary conditions up to a Reynolds number of 20′000. The experimental rig and methodology were firstly tested on a smooth channel and the results were found to be consistent with the literature. The BCC structure with the largest diameter performs the best in terms of heat transfer in view of the higher wetted surface. On the other hand, as expected, the friction factor shows the opposite trend. However, the thermal performance factor does not differ much among the different configurations, with slightly better performances observed for the larger diameter truss. Finally, correlations were found to predict both aero and thermal performances of the considered structure by introducing a modified formulation for the friction factor, Nusselt and Reynolds numbers.

Detach GaN-Based Film to Realize a Monolithic Bifunctional Device for Both Lighting and Detection.

Due to the emerging requirements of miniaturization and multifunctionality, monolithic devices with both functions of lighting and detection are essential for next-generation optoelectronic devices. In this work, based on freestanding (In,Ga)N films, we demonstrate a monolithic device with two functions of lighting and self-powered detection successfully. The freestanding (In,Ga)N film is detached from the epitaxial silicon (Si) substrate by a cost-effective and fast method of electrochemical etching. Due to the stress release and the lightening of the quantum-confined Stark effect (QCSE), the wavelength blueshift of electroluminescent (EL) peak is very small (<1 nm) when increasing the injection current, leading to quite stable EL spectra. On the other hand, the proposed monolithic bifunctional device can have a high ultraviolet/visible reject ratio (Q = 821) for self-powered detection, leading to the excellent detection selectivity. The main reason can be attributed to the removal of Si by the lift-off process, which can limit the response to visible light. This work paves an effective way to develop new monolithic multifunctional devices for both detection and display.

Multifunctional Mesoporous Silica Nanoparticles Reinforced Silk Fibroin Composite with Antibacterial and Osteogenic Effects for Infectious Bone Rehabilitation

Existing implant materials cannot meet the essential multifunctional requirements of repairing infected bone defects, such as antibacterial and osteogenesis abilities. A promising strategy to develop a versatile biomimicry composite of the natural bone structure may be accomplished by combining a multifunctional nanoparticle with an organic scaffold. In this study, a quaternary ammonium silane-modified mesoporous silica containing nano silver (Ag@QHMS) was successfully synthesized and further combined with silk fibroin (SF) to fabricate the multifunctional nano-reinforced scaffold (SF-Ag@QHMS) using the freeze-drying method. Furthermore, the antibacterial and osteogenic effects of this composite were evaluated in vitro and in vivo. SF-Ag@QHMS inherited a three-dimensional porous structure (porosity rate: 91.90 ± 0.62%) and better mechanical characteristics (2.11 ± 0.06 kPa) than that of the SF scaffold (porosity rate: 91.62 ± 1.65%; mechanic strength: 2.02 ± 0.01 kPa). Simultaneously, the introduction of versatile nanoparticles has provided the composite with additional antibacterial ability against Porphyromonas gingivalis, which can be maintained for 15 days. Furthermore, the expression of osteogenic-associated factors was up-regulated due to the silver ions eluting from the composite scaffold. The in vivo micro-CT and histological results indicated that the new bone formation was not only localized around the border of the defect but also arose more in the center with the support of the composite. The multifunctional silver-loaded mesoporous silica enhanced the mechanical strength of the composite while also ensuring greater and sustained antibacterial and osteogenic properties, allowing the SF-Ag@QHMS composite to be used to repair infected bone defects.

Multifunctional Nd2O3/CNFs Composite for Microwave Absorption and Anti-Corrosion Applications

To improve the limitations of traditional microwave absorbing materials (MAMs), such as high density and narrow absorption bandwidth, neodymium oxide/carbon nanofiber (Nd2O3/CNF) composites were successfully prepared by electrospinning technology combined with a high-temperature carbonization process. The three-dimensional network structure of CNFs provides a path for conducting electromagnetic waves, and its porous structure also increases the multiple reflections of electromagnetic waves in the composite fibers, which significantly attenuates the energy of electromagnetic waves. Additionally rare-earth elements have a unique electronic arrangement on the 4f electron layer. The addition of Nd2O3 can turn the dielectric constant of Nd2O3/CNF and optimize the impedance matching. Also, Nd2O3 nanoparticles (Nd2O3–NPs) resulted in numerous of heterojunction surfaces and introduced the magnetic loss mechanism. Under the combined action of the double loss mechanism, the minimum reflection loss of Nd2O3/CNF composite fiber is −66.7 dB at 9.36 GHz, and the effective absorption bandwidth is 4.4 GHz (7.68–12.08 GHz). The radar cross section simulation results also prove that the composite fibers exhibit strong consumption of electromagnetic waves. Additionally, the excellent flexibility and anticorrosion properties of the composite fibers make them satisfy the multifunctional requirements of MAMs.

Radio Resource Allocation for Integrated Sensing, Communication, and Computation Networks

Integrated sensing, communication, and computation (ISCC) will become a key enabler for automation applications. However, since the performance region of ISCC has a higher dimension than those of traditional wireless networks, existing schedulers typically fail to simultaneously meet the heterogeneous requests in ISCC. In this work, we propose a novel wireless scheduling architecture to explore the coordination gains of sensing, communication, and computation from a perspective of joint optimization. Specifically, we first construct an implementation framework of ISCC by combining the mobile edge computing paradigm with the integrated sensing and communication technology, where the inherent tradeoff between sensing, communication, and computation performance is characterized. Next, a joint device association and subchannel assignment problem is formulated to capture the network externalities induced by resource competition among mobile devices with multi-functional requirements. Due to its intractability, we then reformulate it in the matching theoretical manner. To obtain a mutually satisfactory solution under externalities, an iterative matching algorithm is developed by introducing pairwise stability and proved to be convergent and stable. The extensive simulations elucidate the significant superiority of our proposed scheme over those externality-unaware wireless schedulers.

A novel bioinspired architectured materials with interlocking designs based on tessellation

Nature has achieved intricately designed materials with properties and functions that go far beyond the existing engineering materials. The remarkable efficiency of these biological materials is the result of billions of years of evolution. In this study, bioinspired design of architectured materials based on principles of edge-to-edge tessellation is additively manufactured. The tessellations are inspired by the atomic arrangements in cubic metallic crystal structures; simple cubic (SC), body-centered cubic (BCC), and face-centered cubic (FCC). The unit cells in these tessellations were evolved from the basic spherical morphology along with necessary surfaces at the joining area to achieve edge-to-edge tessellations. The biomimetic architectured materials called ‘advanced functional architectured materials (AFAMs)’ are designed and printed with HP-MJF 4200 powder bed fusion technology. The structural and functional properties of each AFAM were evaluated experimentally and numerically under uniaxial compression testing. The result showed FCC AFAM has high peak strength, elastic modulus, and energy absorption compared to other benchmarked surface and truss-based lattice structures. In contrast, SC AFAM demonstrated high deformation (ductility) before densification. The study also reveals that each AFAM behaves uniquely, almost as different material, in terms of its load-bearing and deformation abilities. All the AFAMs can be interlocked without any interface issues to achieve multi-material properties which otherwise cannot be achieved with functionally graded structure. The combination of these AFAMs can be utilized as an efficient solution for achieving a complex set of multi-functional requirements in additively manufactured products. • The novel architectured materials were designed based on the principles observed in nature. • All the architectured materials were edge-to-edge tessellated based on cubic metallic crystal structures: SC, BCC, and FCC. • Each architectured material demonstrates unique strength and ductility/flexibility. • FCC Tessellation shows the highest load-bearing ability and SC tessellation shows the highest deformation. • The designed architectured materials are interlocked into each other for multi-functional properties.

Importance of radial line and circulus distributions to the protectoflexibility of scales in fish armors

Fish scales are dermal armors with an attractive combination of resistance to puncture and flexibility. Past work has attributed this unique quality to their composition and the hierarchical stratification of their microstructure. Here, we show that the ridge lines and circuli of scales contribute to the overall damage tolerance and play a key role in the “protectoflexibility” of fish scales. Through application of optical mechanics, we show that the ridge lines channel damage along paths that reduce the effective stress intensity available for bulk fracture of the scales. Furthermore, comparison of the ridge line distribution and circuli in elasmodine scales shows that they are unique across fish species and appear to be tuned for the combined functional requirements, i.e., resistance to threats and locomotion. The importance of these features in the multifunctional requirements of scales is elucidated in detail, including their role in inspiring new approaches for advancing multifunctional structural materials.

Artificial Intelligence System Detection in English Teaching Based on Heuristic Genetic Algorithm.

Using the traditional English teaching mode is difficult to help correct students, and it is difficult to achieve human-computer interaction in oral English communication. In order to improve the effect of English detection and improve teaching efficiency, this article builds an artificial intelligence-assisted teaching system suitable for English teaching based on heuristic genetic algorithms. Furthermore, this article extends the multioffspring genetic algorithm, improves the offspring generation method, and proposes GMOGA, which makes the choice of the number of offspring more flexible. At the same time, it also enables the value of the number of children of the algorithm to be a value that cannot be obtained by the previous algorithm, which further improves the efficiency of the algorithm. In addition, this article combines the actual needs to construct the functional structure of the artificial intelligence system and designs two sets of comparative experiments to verify and analyze the model's performance. The research results show that the model constructed in this article meets the multifunctional requirements of the system and can be applied to practice.
