Abstract
It is useful to propose a new algorithm to analyze the complicated optimization problems by imitating the function of living things. In this study, it is object to propose new optimization method using the microcosm which is model of natural ecosystem. The microcosm is constituted by considering a bone forming ecosystem that the interaction of each cell is clear and able to be regarded as ecosystem. The optimazation problems are analyzed by the microcosm using GA. The problems is to search the plane structure of the minimum value subjected to a load. Moreover, the validity of design solution is checked for the several design conditions.
