Xiaojun Zhou

摘要:

本文研究了一种新的智能优化算法--离散状态转移算法,用于求解无约束整数最优化问题。首先,总结了离散状态转换算法的一些关键要素,以指导离散状态转换算法的发展。设计了多个智能算子,分别用于局部开发和全局探索。在此基础上,提出了一种动态调整策略“概率风险与恢复”,以获取高概率全局解。最后,通过数值实验对算法的性能进行了测试,并与其他算法进行了比较,结果表明,类似的智能算子可以应用于从流动推销员问题、布尔整数规划到离散值选择问题的求解,体现了所提智能元件的适应性和灵活性.

英文摘要:

A recently new intelligent optimization algorithm called discrete state transition algorithm is considered in this study, for solving unconstrained integer optimization problems. Firstly, some key elements for discrete state transition algorithm are summarized to guide its well development. Several intelligent operators are designed for local exploitation and global exploration. Then, a dynamic adjustment strategy ``risk and restoration in probability" is proposed to capture global solutions with high probability. Finally, numerical experiments are carried out to test the performance of the proposed algorithm compared with other heuristics, and they show that the similar intelligent operators can be applied to ranging from traveling salesman problem, boolean integer programming, to discrete value selection problem, which indicates the adaptability and flexibility of the proposed intelligent elements.
