| Abstract: | Some basic problems in optimal topology designs of structures with discrete variables are studied. The relationship between discrete optimization model and optimum topology solution is discussed and an ignored fact that discrete optimum design may be controlled by the discreteness ofsizing variables and global constraints is pointed out. A heuristic algorithm for solving discrete tology optindzation problems of truss and frame structures is proposed in the present paper. |
