| Abstract(in English) | In this paper, a new optimization method, which is effective for the problems that the optimum solution should be searched in several solution spaces, is proposed. The proposed method is an extension of distributed genetic algorithm (DGA), in which each sub-population searches a solution in the corresponding solution space. During the evolution, "competition" between the sub-populations is performed. Through the competition between the sub-populations, population sizes are adequately and gradually changed. However, An individual converge on the low order solution space before the evaluation value of the high order solution space increase, because the search space in the high order solution space is large and complicated, because the search space in the high order solution space is large and complicated. In this study, we try an improvement of stability by changing the initial population depending on the number of dimensions. |
