Weihrauch degrees of finding equilibria in sequential games (1407.5587v2)
Published 21 Jul 2014 in cs.LO and cs.GT
Abstract: We consider the degrees of non-computability (Weihrauch degrees) of finding winning strategies (or more generally, Nash equilibria) in infinite sequential games with certain winning sets (or more generally, outcome sets). In particular, we show that as the complexity of the winning sets increases in the difference hierarchy, the complexity of constructing winning strategies increases in the effective Borel hierarchy.
