Abstract. In this paper, architectural constructions composed of spatial truss units are considered by using a new technique of artificial life. Such spatial truss structure has flexibility and adaptability to environments. At first, equilateral tetrahedral (regular tetrahedral) units, which are basic space units having three dimensions, are proliferated to specified directions at random. At every proliferation step, various architectural evaluations and selections are performed according to obtained degrees of adaptation to environments. The purpose of this paper is to compose a system for a variety of automatical formation, which satisfies the given architectural and environmental conditions by using Genetic Algorithm (GA) originated by HOLLAND and GOLDBERG. The effectiveness of the proposed system is shown by digital and graphical simulations.
