| Abstract: | In this paper, aiming at the phenomenon of mixed-discrete variables which generallyexists in ship structural optimum design, an improved genetic algorithm is introduced tosearch directly an optimal solution. The results of two examples show the genetic algorithm can solve efficientIy the problems of ship structural optimum design with mixed-discrete variables. |
