摘要：为分析、计算多目标优化设计的电磁场逆问题，提出了矢量禁忌优化算法。在矢量禁忌算法中，应用接触理论判断Pareto最优解、应用排序法确定可行解的适值。为保证搜索到的Pareto最优解均匀分布于目标函数和决策变量空间，提出了一种简单、有效的适值共享函数。通过典型算例的验证，可以看出，对于多目标优化设计问题，所提出的矢量禁忌能够搜索到均匀、平滑的Pareto曲线，由此可见，矢量禁忌算法可实际运用于复杂工程电磁场逆问题的分析和计算。

Abstract: To find out the Pareto solutions of multiobjective optimal design problems arising from inverse electromagnetic problems, a tabu search method was proposed. For this goal, the contact theorem was used to determine the Pareto solutions. To scale the multiobjective in sense of Pareto optimal, the ranking approach was used and the fitness sharing function was introduced to guarantee the diversity of the searched Pareto solutions in both parameter and objective spaces. Numerical results are reported to demonstrate the power of the proposed algorithm in ensuring uniform sampling and obtaining the Pareto optimal front of the multiobjective design problems.
Key words: multiobjective optimization; tabu search method; vector optimal method; inverse electromagnetic problems
