Various techniques are proposed in order to make the optimal structures according to the design objects. GA is one of the optimization techniques imitating the mechanism of life evolution. However, on the GA, it is difficult to obtain the optimal solution for the limit of coding on the large-scale problems. Then, the method combining GA with L-system, that is a form generating mechanism of a cell, is proposed. It is an evolutionary technique to obtain the optimal solutions according to the design objects and called as the evolutionary L-system (ELS). In this research, the optimum truss layouts problems are analyzed by using ELS.
