| Research Abstract |
In this research, first of all, the habitat segregation concerning the use of the life like approach and mathematical programming was clarified. Next, the decent solution was defined by this research. The decent solution showed the importance in the structural design field. The decent solution is a solution with a comparatively high evaluation that contains the global optimum and the local optimum. The life like approach uses the genetic algorithm and the cellular automaton. Especially, we proposed the decent solution search algorithm by the genetic algorithm. The decent solution search can grasp the entire solution space. In addition, the decent solution search becomes a strong means for the structural morphogenesis problem. A trial system of the conception support and the design aid was developed based on these solution search algorithms. The developed system applied to the structural morphogenesis problem. The analysis result was able to search for a lot of structural forms with a lucid flow of force. These results are given choices that structurally stabilize for the designer and are wide, and are presentations of a new idea that stimulates the designer's conception. Therefore, a first purpose of the structural morphogenesis with diversity was able to be achieved.
