Abstract

Genetic algorithm with sharing (D.E. Goldberg and J. Richardson, 1987) shows that it can restrain from individuals converging to the global minimum and maintain the diversity of the individuals. However, there is room for improvement in the sharing method. In this paper, a new genetic algorithm named Genetic Symbiosis Algorithm (GSA) is proposed to overcome the problems of the conventional method. GSA is based on the symbiosis concept found widely in ecosystems. Simulation studies show that GSA can produce a great variety number of individuals that have each special characteristics.
