摘要:

在多智能体路径查找(MAPF)问题中,智能体可能会因意外事件而延迟。为了解决这种情况下,最近的工作描述了k-鲁棒的基于搜索(k-CBS):一种算法,产生协调和无冲突的计划,是强大的k延迟。在这项工作中,我们引入了各种成对的对称破缺约束,具体到k-鲁棒规划,可以有效地找到兼容的和最佳的路径对冲突的代理。我们对新的限制进行了全面的描述,并报告了一系列领域的成功率的大幅提高,包括:(i)经典的MAPF基准;(ii)自动化仓库领域;(iii)2019年平地挑战赛的地图,最近推出的铁路领域,k-鲁棒规划可以有效地应用于调度列车。

英文摘要:

During Multi-Agent Path Finding (MAPF) problems, agents can be delayed by unexpected events. To address such situations recent work describes k-Robust Conflict-BasedSearch (k-CBS): an algorithm that produces coordinated and collision-free plan that is robust for up to k delays. In this work we introducing a variety of pairwise symmetry breaking constraints, specific to k-robust planning, that can efficiently find compatible and optimal paths for pairs of conflicting agents. We give a thorough description of the new constraints and report large improvements to success rate ina range of domains including: (i) classic MAPF benchmarks;(ii) automated warehouse domains and; (iii) on maps from the 2019 Flatland Challenge, a recently introduced railway domain where k-robust planning can be fruitfully applied to schedule trains.
