The Renyi-Ulam pathological liar game with a fixed number of lies
Abstract
The -round Renyi-Ulam pathological liar game with lies on the set is a 2-player perfect information zero sum game. In each round Paul chooses a subset and Carole either assigns 1 lie to each element of or to each element of . Paul wins if after rounds there is at least one element with or fewer lies. The game is dual to the original Renyi-Ulam liar game for which the winning condition is that at most one element has or fewer lies. We prove the existence of a winning strategy for Paul to the existence of a covering of the discrete hypercube with certain relaxed Hamming balls. Defining to be the minimum such that Paul can win the -round pathological liar game with lies and initial set , we find and exactly. For fixed we prove that is within an absolute constant (depending only on ) of the sphere bound, ; this is already known to hold for the original Renyi-Ulam liar game due to a result of J. Spencer.
