The new FIFA rules are hard : complexity aspects of sports competitions.

Kern, W. and Paulusma, D. (2001) 'The new FIFA rules are hard : complexity aspects of sports competitions.', Discrete applied mathematics., 108 (3). pp. 317-323.

Abstract

Consider a soccer competition among various teams playing against each other in pairs (matches) according to a previously determined schedule. At some stage of the competition one may ask whether a particular team still has a (theoretical) chance to win the competition. The complexity of this question depends on the way scores are allocated according to the outcome of a match. For example, the problem is polynomially solvable for the ancient FIFA rules ( resp. ) but becomes NP-hard if the new rules ( resp. ) are applied. We determine the complexity of the above problem for all possible score allocation rules.
