In the previous papers we proposed a method for shape and topology optimization (i.e., layout optimization) of two-dimensional finite element models of mechanical structures using genetic algorithm. The method is contrived in such a way that optimal layouts are obtained by selecting the layouts of the models as individuals, and by adopting removal and addition parameters of the elements as chromosomes. A certain relationship between the both parameters are certified to exist in various experiments. We, therefore, proposed a finite-difference-type of sensitive optimal method using the relationship, which can be called a deterministic GA approach with a single individual. It is demonstrated that the final layouts obtained by the approach are similar to those gained by GA and cellular automaton.
