PSPACE-Completeness of Multi-Agent Path Finding for Large Agents

Maichi Zhang, Naoyuki Kamiyama, Kanae Yoshiwatari

Multi-Agent Path Finding for Large Agents (LA-MAPF) is a geometric variant of MAPF in which agents are modeled as disks and conflicts are determined by physical overlap in the unde…

Reforming an Unfair Allocation by Exchanging Goods

Sheung Man Yuen, Ayumi Igarashi, Naoyuki Kamiyama +1

Fairly allocating indivisible goods is a frequently occurring task in everyday life. Given an initial allocation of the goods, we consider the problem of reforming it via a sequenc…

The Strongly Stable Roommates Problem and Linear Programming

Naoyuki Kamiyama

The stable roommates problem is a non-bipartite version of the stable matching problem in a bipartite graph. In this paper, we consider the stable roommates problem with ties. In p…
