| 摘 要： | 介绍了实值优化问题的进化算法，自然进化是基于群体的优化过程，在计算机上模拟自然进化过程形成统计优化技术．同传统优化方法相比，进化算法具有全局优化的优点，而且适合复杂的实际问题．带宽优化是寻找结点编号的最佳排列，使得刚度矩阵的带宽最小．传统方法一般求得带宽的局部极小值，而带宽优化进化算法可求得带宽的全局最优解

| Abstract: | A simulated evolutionary algorithm is introduced for real valued function optimization. Natural evolution is a optimization process based on population. Simulating this process on a computer has led to stochastic optimization techniques. Compared with classical methods,a simulated evolutionary algorithm converges to global optimum,fits for complex practical problems. Bandwidth optimization is for searching agrid a optimum grid point sequence,so as to obtain minimum bandwidth. Classical methods generally converge to local minimum bandwidth,while the simulated evolutionary algorithm can seach the global optimum solution. |
