This paper introduces “population migration” idea and proposes an improved multi-population genetic algorithm based on population migration, which differed from tradition multi-population genetic algorithms that only improve the crossover and mutation operator. The new algorithm provides a population adjusting strategy based on population migration to adjust the population size automatically. Firstly,...
Side-chain positioning is a central component of homology modeling and protein design. A simple solution is introduced by assuming a fixed backbone and discretizing the amino acid side-chain conformations into energetically favorable rotamers. For each possible combination of rotamers, an energy function is used to evaluate its fitness for the target conformation. While constructing complete energy...
