摘要:

联盟结构形成问题是多智能体系统中一个活跃的研究领域。一个联盟结构被定义为一个分区的代理人参与到一个系统不相交的联盟。寻找最优联盟结构的问题是NP完全的。为了在组合优化问题中找到最优解,理论上可以枚举解并对每个解进行评估。但这种方法是不可行的,因为解决方案的数量往往随着问题的大小呈指数增长。在本文中,我们提出了一个贪婪的自适应搜索过程(GRASP),有效地搜索空间的联盟结构,以找到一个最佳的。实验和与其他算法的比较证明了该方法在解决这一组合难题中的有效性。

英文摘要:

The coalition structure formation problem represents an active research area in multi-agent systems. A coalition structure is defined as a partition of the agents involved in a system into disjoint coalitions. The problem of finding the optimal coalition structure is NP-complete. In order to find the optimal solution in a combinatorial optimization problem it is theoretically possible to enumerate the solutions and evaluate each. But this approach is infeasible since the number of solutions often grows exponentially with the size of the problem. In this paper we present a greedy adaptive search procedure (GRASP) to efficiently search the space of coalition structures in order to find an optimal one. Experiments and comparisons to other algorithms prove the validity of the proposed method in solving this hard combinatorial problem.
