Integer Programming for Multi-Robot Planning: A Column Generation Approach [article]

Naveed Haghani, Jiaoyang Li, Sven Koenig, Gautam Kunapuli, Claudio Contardo, Julian Yarkony
2020 arXiv   pre-print
Since the set of robot routes is not enumerable, we attack optimization using column generation where pricing is a resource-constrained shortest-path problem.  ...  We formulate the problem as a weighted set packing problem where elements are defined as being the space-time positions a robot can occupy and the items that can be picked up and delivered.  ...  Routing problems for a fleet of robots in a warehouse are often treated as Multi-Agent Pathfinding problems (MAPF) (Stern et al. 2019) .  ...

Graph Abstraction in Real-time Heuristic Search

V. Bulitko, N. Sturtevant, J. Lu, T. Yau
2007 The Journal of Artificial Intelligence Research  
Such agents plan only a few actions at a time in a local search space and avoid getting trapped in local minima by improving their heuristic function over time.  ...  We then analyze the impact of abstraction in an extensive empirical study in real-time pathfinding.  ...  This research has been enabled by the use of WestGrid computing resources, which are funded in part by the Canada Foundation for Innovation, Alberta Innovation and Science, BC Advanced Education, and the  ...

Robust Multi-Agent Path Finding and Executing

Dor Atzmon, Roni Stern, Ariel Felner, Glenn Wagner, Roman Barták, Neng-Fa Zhou
2020 The Journal of Artificial Intelligence Research  
Multi-agent path-finding (MAPF) is the problem of finding a plan for moving a set of agents from their initial locations to their goals without collisions.  ...  We propose sufficient and required conditions for finding a k-robust plan, and show how to convert several MAPF solvers to find such plans.

Multi-Agent Path Finding: A New Boolean Encoding

Roberto Asín Achá, Rodrigo López, Sebastian Hagedorn, Jorge A. Baier
2022 The Journal of Artificial Intelligence Research  
Multi-agent pathfinding (MAPF) is an NP-hard problem. As such, dense maps may be very hard to solve optimally.  ...  We compared against representative solvers of the state-of-the-art, including the search-based algorithm CBS, the ASP-based solver ASP-MAPF, and the branch-and-cut-and-price hybrid solver, BCP.  ...  Introduction Given a graph G and K agents, each of which is associated with a start and a goal vertex of G, multi-agent pathfinding (MAPF) is the problem of finding K non-conflicting paths π 1 , . . .  ...
