摘要
和声搜索具有不需要初始值,利用随机搜索代替梯度搜索,而无需更多信息的优点。以和声搜索算法为工具,建立管网优化的数学模型,以费用最小作为目标函数对配水系统管网设计进行管径寻优。并以Hanoi管网为例,将和声搜索算法同经典遗传算法进行比较。计算结果表明和声搜索算法在管网优化设计中有着很好的前景。
This paper describes a new meta-heuristic algorithm, called the harmony search （HS）, which was conceptualized using the musical process of searching for a perfect state of harmony. The HS algorithm does not require initial values and uses a random search instead of a gradient search, so derivative information is unnecessary. This study focused on pipe diameter optimization while minimizing design cost, then compared the results of HS with genetic algorithm. The results are very promising and demonstrate the usefulness of harmony search algorithms in solving this kind of optimization problem.
