1、多目标优化问题及其算法的研究摘要:多目标优化问题MOP由于目标函数有两个或两个以上,其解通常是一组Pareto最优解。传统的优化算法在处理多目标优化问题时不能满足工业实践应用的需要。随着计算机科学与生命信息科学的发展,智能优化算法在处理多目标优化问题时更加满足工程实践的需要。本文首先研究了典型多目标优化问题的数学描述,并且分析了多目标优化问题的Pareto最优解以及解的评价体系。简要介绍了传统优化算法中的加权法、约束法以及线性规划法。并且研究了智能优化算法中进化算法EA、粒子群算法PSO和蚁群优化算法ACO.关键词:多目标优化问题;传统优化算法;进化算法;粒子群算法;蚁群优化算法中图分类号:T

6、标函数的最优化解。当优化的目标函数为一个时称之为单目标优化Single-objective Optimization Problem, SOPo当优化的目标函数有两个或两个以上时称为多目标优化Multi-objective OptimizationProblem, MOPo不同于单目标优化的解为有限解,多目标优化的解通常是一组均衡解。显而易见,多目标优化问题比单目标优化问题更接近工程实践,同时更加复杂。很多工程实践中的优化问题最后都可以转化为多目标优化问题。因此,对多目标优化问题的深入研究对于实践应用更具价值。通常,多目标优化问题都是通过一定的算法实现求解的。对多目标优化问题的研究也更多地集中
