A hunger game search algorithm for economic load dispatch

This work proposes a new approach to solve the economic load dispatch (ELD) issue in power systems by metaheuristic algorithms inspired by natural life. The problem to be resolved is to optimize the power system network with various constraints by considering the cutting in the cost of the resulting in the transmission of the electric system. The method used in this study is the hunger games search (HGS). This method duplicates the hungerdriven activity and the animal's choice of behavior. The proposed method is to add the concept of starvation as a process structure. Adaptive weights based on the concept of hunger are designed and used to simulate the effects of hunger on each trace process. To get the performance of the proposed method, this research uses mathematical methods, particle swarm optimization (PSO), differential evolution (DE), giza pyramids construction (GPC), and sine tree-seed algorithm (STSA) as a comparison. This study uses 2 case studies. In case study 1, the proposed method has a 0.16% better cost of generation than the mathematical method. Comparison of the HGS method with the PSO method in the second case study, it was found that the HGS method was 0.018% better than the PSO. From the research, it was found that the HGS method was superior.

Emerging Community Pantries in the Philippines during the Pandemic: Hunger, Healing, and Hope

This research is a critical approach to the emergence of community pantries during the COVID-19 pandemic as at-once contestatory and transformative narratives, foregrounding the Filipino poor’s experience of hunger, suffering, and marginality, while also highlighting their collective hope for a better world. I began by exploring the emergence of the community pantry in the Philippines, which was prompted by the government’s inadequate response to the plight of the hungry poor due to prolonged mandatory lockdown in the National Capital Region. I then turned to Emmanuel Levinas’ concept of hunger as the basis for the ethical giving displayed in the community pantries, which is a symbolic arena where leadership is questioned and the marginalized voices of the hungry poor are both mainstreamed and articulated. I brought ethical giving into relation with the Jewish concept of Tikkun Olam as the platform for the possibility of healing wounded relations. I constructed a particular weave between the community pantry and the Filipinos’ shared experiences of hunger that touches on the ethical that can create liberating spaces for collective hope. In conclusion, I argue that this study is valuable for confronting unexamined assumptions of the relationship between hunger, healing, and hope for critical pedagogy and critical spirituality, which can have significant philosophical and theological implications.

HSWOA: An ensemble of hunger games search and whale optimization algorithm for global optimization

The search for food stimulated by hunger is a common phenomenon in the animal world. Mimicking the concept, recently, an optimization algorithm Hunger Games Search (HGS) has been proposed for global optimization. On the other side, the Whale Optimization Algorithm (WOA) is a commonly utilized nature-inspired algorithm portrayed by a straightforward construction with easy parameters imitating the hunting behavior of humpback whales. However, due to minimum exploration of the search space, WOA has a high chance of trapping into local solutions, and more exploitation leads it towards premature convergence. The concept of hunger from HGS is merged with the food searching techniques of the whale to lessen the inherent drawbacks of WOA. Two weights of HGS are adaptively designed for every whale using the respective hunger level for balancing search strategies. Performance verification of the proposed hunger search-based whale optimization algorithm (HSWOA) is done by comparing it with 10 state-of-the-art algorithms, including three very recently developed algorithms on 30 classical benchmark functions. Comparison with some basic algorithms, recently modified algorithms, and WOA variants is performed using IEEE CEC 2019 function set. Statistical performance of the proposed algorithm is verified with Friedman's test, boxplot analysis, and Nemenyi multiple comparison test. The operating speed of the algorithm is determined and tested with complexity analysis and convergence analysis. Finally, seven real-world engineering problems are solved and compared with a list of metaheuristic algorithms. Numerical and statistical performance comparison with state-of-the-art algorithms confirms the efficacy of the newly designed algorithm.

Psychometric evaluation of the DAILY EATS questionnaire in individuals living with obesity

BackgroundPhysiological and behavioral factors including hunger, satiety, food intake, and cravings are health determinants contributing to obesity. Patient-reported outcome (PRO) measures focused on eating-related factors provide insight into the relationships between food choice and quantity, weight change, and weight-loss treatment for individuals living with obesity. The DAILY EATS is a novel 5-item, patient-reported measure evaluating key eating-related factors (Worst and Average Hunger, Appetite, Cravings, and Satiety).MethodsPsychometric analyses, consistent with regulatory standards, were conducted to evaluate the DAILY EATS using data from two randomized trials that included individuals with severe obesity without diabetes (NCT03486392) and with severe obesity and type 2 diabetes (NCT03586830). Additional measures included Patient Global Impression of Status (PGIS) and Patient Global Impression of Change items, Impact of Weight on Quality of Life-Lite, Ease of Weight Management, and Patient-Reported Outcomes Measurement Information System Physical Function Short Form 8b and 10a. The reliability, validity, and responsiveness of the DAILY EATS were assessed, and a scoring algorithm and thresholds to interpret meaningful score changes were developed.ResultsItem-level analyses of the DAILY EATS supported computation of an Eating Drivers Index (EDI), comprising the related items Worst Hunger, Appetite, and Cravings. Internal consistency (Cronbach’s coefficient alphas ≥0.80) and test-retest reliability (coefficients > 0.7) of the EDI were robust. Construct validity correlation patterns with other PRO measures were as hypothesized, with moderate to strong significant correlations between the EDI and PGIS-Hunger (0.30 ≤ r ≤ 0.68), PGIS-Cravings (0.33 ≤ r ≤ 0.77) and PGIS-Appetite (0.52 ≤ r ≤ 0.77). Anchor- and distribution-based analyses support reductions ranging from 1.6 to 2.1 as responder thresholds for the EDI, representing meaningful within-person improvement.ConclusionsThe DAILY EATS individual items and the composite EDI are reliable, sensitive, and valid in evaluating the concepts of hunger, appetite, and cravings for use in individuals with severe obesity with or without type 2 diabetes.

Choosing hunger

In much of the academic literature, hunger is treated as a problematic condition that affects people against their will. However, this focus ignores the many instances in which people actively choose to go hungry. The clearest examples are cases – such as dieters, hunger artists, and religious fasters – in which the choice seems voluntary. Yet people forced into famine or starved in concentration camps also make critical, though often subtle trade-offs related to hunger. This paper explores two fundamental characteristics that help to clarify the differences between various cases of hunger: the degree of choice and the severity of the consequences. By emphasizing the centrality of choice and providing a framework for the analysis of various situations, the paper argues for a re-examination of the concept of hunger.

From Hunger to Food Security: A Conceptual History

Hunger afflicts hundreds of millions of people around the world. However, the very concept of hunger is difficult to define, and in fact the whole issue of hunger has been subsumed under the more comprehensive concept of food security.This paper retraces the history of this concept, from its original appearance in international usage at the 1974 World Food Conference, to more modern versions like the definition adopted in the First and subsequent World Food Summits. Originally framed in terms of sufficient world supply of food, the concept of food security initially morphed into the aim of national self-sufficiency in the production of food, but later evolved into its current meaning centred on access to food by individuals and households. Under its more recent incarna­tion, and quite unlike its former meaning, it is recognised that international food trade is a key element for achieving food security. This and other conceptual transformations are revised through this paper.

A new way of looking at eating

the analysis of meals, especially of spontaneous meals, has long had a problematic place in the behavioral neuroscience of eating. Only a small minority of eating researchers now, or ever, have concerned themselves with meal patterns. On first glance this seems paradoxical. After all, eating occurs

Évolution historique des concepts de faim, satiété et appétits

This thesis is the most important work about the historical changes in the concepts of hunger, satiety and appetite. Across the four hundred and twenty pages and the five hundred and forty references, the author reports the point of view of philosophs, naturalists, scientists, physiologists and pathologists concerning this concepts. This study begins in the early times of prehistory and finishes actually. The nutritionnals aspects take place in the beginning of the nineteen century with F. Magendie, F. Longet, P. Flourens and Cl. Bernard. The discovery of the feeding centers dates of 1940's with the works J. Mayer, Heterington and Ranson, Anand and Bbrobeck, and J. Le Magnen.

Depensatory Process Based on the Concept of Hunger

In a recent paper by Larkin et al. (1964) reproduction curves are considered for life history stanzas, and a depensatory process related in form to the compensatory process of Ricker (1954) is presented. In the following development the necessity of defining such functions as two parameter systems is presented. A theoretical production curve based on the concept of hunger is derived. It is also shown that under conditions of extreme predation this curve approximates Larkin's depensatory production curve. The curve is applied to data for Adams River sockeye salmon.
