| Abstract: | In order to improve the performance of immune algorithm,chaos optimization was integrated into immune clone selection algorithm.The importance of the selection probability of antibody was analyzed and its varied calculated equation was given.The changeable rate of fitness by antibodies 3 times continuous generations was adopted to regulate antibody selection probability value adaptively.The concrete steps for the optimization method of hybrid chaos immune algorithm with self-adaptive parameter adjusting was given.To compare the performance of optimization method of hybrid chaos immune algorithm with self-adaptive parameter adjusting,immune clone selection algorithm and traditional method in the literatures,three methods were used to optimize the main beam cross-section for crane structure.Comparison results indicate that the optimization method of hybrid chaos immune algorithm with self-adaptive parameter adjusting has many advantages such as better self-adaptive capacity,higher computation efficiency and design accuracy. |
