摘要
基于并行遗传算法将软件系统的可靠性优化问题表达为一类带约束条件的组合优化问题,并采用并行遗传算法中的岛屿模型和迁移策略,较好地改善了搜索性能。模拟实验表明:并行遗传算法有效地提高了运行速度和求解质量。
This paper is based on parallel genetic algorithm. The reliability optimization problem in terms of software system is converted into a kind of nonlinear optimation problem with a large number of constraints. Furthermore, it greatly improves the search performance on using the island model and migration policy. The imitate results manifest that the algorithm can effectivelv imnrove the comnuting speed and the resolution quality.
