问题是否是Complete的 / 问题是否能被解到Optimality
NP-hardness 及其证明省略。
一些简要的记录
- 证明了:同时最小化总时间、最小化最晚到达时间这几个目标,是不可能的。(
optimality cannot always be simultaneously achieved for minimum makespan and minimum total arrival time.

LaValle, Structure and Intractability of Op-timal Multi-Robot Path Planning on Graphs. presented atthe Twenty-Seventh AAAI Conference on Artificial Intelli-gence, Jun. 2013, Accessed: Jul. 27, 2020. [Online]. Available:https://www.aaai.org/ocs/index.php/AAAI/AAAI13/paper/view/6111. 这个文章同样提到的是Multi-robot Path Planning on Graphs with Parallel Moves and Rotations问题。 \(MPP_{pr}\) Problem
- 4-Connected Grid
- 一个精准的描述:二维网格。
- WHCA (Windowed Hierarchical Cooperative A algorithm)
- 每次预测未来几步要走的路径,然后没到目的地的话就再规划。 Code(Not verified)
- Kornhauser’s algorithm
- Complicated? 没有找到具体的描述诶。
- Push And Swap algorithm
- 参考链接。基于局部的路径进行调整。Code (这个课程汇报的小哥做得也太强了吧...)
- Well-performed
- 评价算法表现的指标。
- Solidable
- 评价表现的指标。
- Sam Loyd’s 15-puzzle
- 这不就是华容道?Wolfram Intro.
