Optimum topology problem of two-dimensional structures using genetic algorithm

Recently, there are many studies on shape optimization and some of them have provided practical tools. Unexpectedly, there are not very many studies on determining the optimum topology, in comparison with those on shape optimization techniques. Therefore, in this study, we propose a method of finding optimum topologies of 2-dimensional structures using the genetic algorithm (GA). In this report, we propose a basic method, a method which comprises multistage finite-element partitioning and adopts the allocation of genes. We apply the proposed algorithm to some examples and examine their effectiveness.
