In this paper we present hierarchical chromosome based genetic algorithm and its application to solving of exemplary design problem-optimization of platform with minimal overall volume and the stress value not greater then the maximum admissible value, when the platform is under the external load. The algorithm uses hierarchical chromosome representation and hierarchical genetic operators, instead of the binary representation and traditional genetic operators. It allows for coding of phenotypes with different number of components as well as performing reproduction with such individuals. In order to solve the problem, the application with hierarchical chromosome based genetic algorithm was interfaced with the parallel fully automatic hp adaptive 3D Finite Element Method package (parph3D). The parph3D application was used to compute the stress values for individuals generated by genetic algorithm.
