Abstract
Protein Structure Prediction (PSP) is an NP-hard optimization problem that has been solved by many existing algorithms. Simply, it can be thought of a process of predicting the native 3D structure from its amino acid sequence. Chemical Reaction Optimization (CRO) is a recent metaheuristic algorithm that has been applied to many well-known problems and has shown better performance compared to the existing ones. So, we have applied CRO algorithm to solve the PSP problem. The four operators of CRO: on-wall ineffective collision, decomposition, inter-molecular ineffective collision, and synthesis have been designed to solve PSP problem. We have also designed a repair mechanism to get the correct structure. The experiment results show that CRO performs well in the case of PSP.
