Abstract
AbstractIn this work we show an innovative approach to the protein folding problem based on an hybrid Immune Algorithm (IA) and a quasi-Newton method starting from a population of promising protein conformations created by the global optimizer DIRECT. The new method has been tested on Met-Enkephelin peptide, which is a paradigmatic example of multiple-minima problem, 1POLY, 1ROP and the three helix protein 1BDC. The experimental results show as the multistage approach is a competitive and effective search method in the conformational search space of real proteins, in terms of quality solution and computational cost comparing the results of the current state-of-art algorithms.KeywordsDeterministic SearchDIRECTImmune AlgorithmsClonal Selection AlgorithmsQuasi-Newton methodHybrid methodsProtein FoldingProtein Structure PredictionBioinformatics
