摘要
传统优化算法对于解决平面四杆机构函数综合等复杂非线性约束优化问题存在局部收敛等不足。分析了混沌的特性及在优化方面的应用 ,建立了混沌与传统Powell法结合的混合算法。计算实例表明 ,该方法全局收敛性好 ,搜索效率高 。
Traditional optimizations have disadvantages such as local convergence when they are used to solve function synthesis of planar 4-bar linkage, which is a complex nonlinear constraint problem. Features of chaos and its applications on optimization are analyzed, and a mixed chaos optimization combining Powell method is found. The instances indicate that the algorithm has excellent convergence property and high efficiency,it is a good method to solve complex nonlinear constraint engineering problems.
