摘要: 在传统的遗传算法中引入一种基于频率矩阵的种群多样性策略.该频率矩阵记 录了从初始种群到局部最优解搜索过程中得到的具有相同特征解出现的频率,从而给跳 出局部最优解,拓展解空间提供了有用的启发信息.将这种策略应用于求解二次布局问题 中取得了令人满意的结果.

Abstract: A frequency-based matrix diversity strategy is applied in the traditional Genetic Algorithm.The frequencybased matrix recorded the appearance frequency of the special solution from the initial solution to the local optimized solution.So it can supply some useful information to help GA jump out of the local optimized solution.We apply this strategy to the GA for quadratic assignment problem and get satisfied results.

Key words:  genetic algorithm, frequency-based matrix, diversity, quadratic assignment problem, local optimized solution
