摘    要:多目标优化问题是目前遗传算法应用研究的一个重点。本文针对经典遗传算法在多目标优化计算中,难以获得足够的比较均匀的Pareto优集的不足,提出一种热力学遗传算法,研究热力学中熵和温度的概念,并综合利用约束交叉、适应度共享技术来进行目标函数的优化计算。实验结果显示,这种改进型遗传算法能得到一个较好的Pareto优集。

关 键 词:多目标优化    遗传算法  模拟退火算法

Abstract:Multiobjective optimization is one of the main research fields of genetic algorithm, hut it is hard to get adequate and well - distributed optimal solutions when traditional genetic algorithm is used. In this paper, we propose a thermodynamical genetic algorithm in which the concepts of temperature and entropy in thermodynamics are used and are combined with the Pareto - based ranking and fitness sharing. The experiment results show that this algorithm can find a better of Pareto optimal solutions.
Keywords:Genetic algorithm Multiobjective optimization Pareto optimal solutions Entropy Thermodynamical genetic algorithm
