Studies have been conducted in the application of Genetic Algorithms (GAs) to this problem with initial results shown to be promising. In this paper we use the fast messy Genetic Algorithm (fmGA) to attempt to find the minimization of an empirical CHARMM energy model and generation of the associated conformation. Previous work has shown that the fmGA provided favorable results, at least when applied to the pentapeptide [Met]-Enkephelin. We extend these results to a much larger Polyalanine peptide by utilizing secondary structure information. This information is utilized to conduct localized searches on the energy landscape. Results indicate that on average this localized search always produces a better final solution. |  | View paper | | ISBN: | 0-9708275-3-9 |
