摘要: 重叠联盟结构生成(OCSG)的解空间复杂性较高,基于演化计算的随机搜索方法不能保证得到最优解,且其假设Agent承担任务消耗资源时不产生任何成本代价,导致无法区分各联盟结构的差异性。针对该问题,构建以联盟结构成本最小化为优化目标的OCSG数学模型,并提出一种基于动态规划的最优OCSG算法。实验结果表明,与TTGs_DP算法相比,该算法的环境适应性较好,资源利用率较高。

Abstract: The solution space complexity of Overlapping Coalition Structure Generation(OCSG) is high.The stochastic search method based on evolutionary computation can not guarantee the optimal solution,and it assumes that the Agent does not incur any cost when it undertakes the task to consume resources,which makes it impossible to distinguish the differences among coalition structures.To solve this problem,an OCSG mathematical model with the objective of minimizing the cost of coalition structure is constructed,and an optimal OCSG algorithm based on dynamic planning is proposed.Experimental results show that compared with TTGs_DP algorithm,this algorithm has better environmental adaptability and higher resource utilization rate.
