摘要
针对大型复杂系统的测试序贯设计问题,首次提出利用基于混合策略的差分进化算法(DE)进行测试序贯设计。通过LOV规则,将实数空间映射到表示测试序贯的离散空间;利用随机变异策略和小概率扰动操作,进一步加强了算法的探索能力和开发能力;局部动态搜索算子的引入,提高了算法的收敛速度。通过实例和其他常用算法进行了对比,验证了该算法的有效性。
For testing sequence design of large complex system,a differential evolution algorithm （DE）based on a hybrid strategy was proposed firstly.By LOV rules,real space was mapped to a discrete apace of testing sequence;The random mutation strategy and perturbation of small probability strengthened the exploration and development of the algorithm;The local dynamic operator was introduced to improve the convergence rate.Through an example other algorithms were compared to verify the effectiveness of the algorithm.
