The present work describes recent advances made in the system for 3-D structure prediction of polypeptidesbeing developed in our laboratory. The system was originally conceived as a conformational space searchprocedure based on a simple genetic algorithm. However, the complexity of the system and the need toproduce better fit conformers as artificial evolution proceeds, compelled us to improve the algorithm in twosubstantial aspects. The first is a parallelization of the original algorithm...
