摘要： 提出一种修正和声搜索(MHS)算法，并对结构设计问题进行了求解.MHS应用了新的位置更新以增强算法的解空间开发能力，并运用等效微分策略调整和声微调步长，提高算法的寻优精度，增强算法跳出局部最优的能力.为了表明MHS的有效性，对3种结构设计优化问题进行了测试，结果显示MHS优于其他4种和声搜索算法，并与最近文献报道的最优值进行比较，表明MHS在解决结构设计优化问题中能够找到更好的解.

关键词: 修正和声搜索算法, 结构设计, 位置更新, 等效微分, 有效性

Abstract: A modified harmony search (MHS) algorithm was proposed to solve structural design problem. A novel position updating operator was applied to enhance the development capability of solution space. Equivalent differential strategy was used to adaptively adjust harmony distance bandwidth， which could improve the searching accuracy and escape the local optima. To confirm the MHS effectiveness， three structural design optimization problems were tested. The tests demonstrated that MHS had better result than that of other four harmony search algorithms. Comparing with the best solution reported in recent literature， the MHS could find out better solutions to the optimization problem of structural design.

Key words: MHS, structural design, position updating, equivalent differential, effectiveness
