Growth of Dimension in Complete Simple Games (1605.05114v1)
Published 17 May 2016 in cs.GT
Abstract: The concept of dimension in simple games was introduced as a measure of the remoteness of a given game from a weighted game. Taylor and Zwicker (1993) demonstrated that the dimension of a simple game can grow exponentially in the number of players. However, the problem of worst-case growth of the dimension in complete games was left open. Freixas and Puente (2008) showed that complete games of arbitrary dimension exist and, in particular, their examples demonstrate that the worst-case growth of dimension in complete games is at least linear. In this paper, using a novel technique of Kurz and Napel (2016), we demonstrate that the worst-case growth of dimension in complete simple games is exponential in the number of players.
