Abstract: Protein structure prediction (PSP) is one of the most challenging problems nowadays and an important Bioinformatics research topic. In this paper we propose an optimization method based on differential evolution for PSP problem. We model PSP as an optimization problem in order to minimize the potential energy using ab initio approach. This problem is handled here as multi-objective optimization, and it is solved by the evolutionary method of Differential Evolution (DE). An innovative way of choosing the best individual of the population is proposed in this work: the minimum distance to the empirical ideal point. The idea is to guide the population individuals to areas of the Pareto front that correspond to a good compromise of the bonded and non-bonded energies. The proposed approach is validated on some peptides with promising results.
