Multinational War is Hard

Computational Complexity 2015-03-11 v3

Abstract

In this paper, we show that the problem of determining whether one player can force a win in a multiplayer version of the children's card game War is PSPACE-hard. The same reduction shows that a related problem, asking whether a player can survive k rounds, is PSPACE-complete when k is polynomial in the size of the input.
