A note on “Banks winners in tournaments are difficult to recognize” by G. J. Woeginger

Social Choice and Welfare, 2004, vol. 23, issue 1, 113-114

Abstract: Given a tournament T, a Banks winner of T is the first vertex of any maximal (with respect to inclusion) transitive subtournament of T. While Woeginger shows that recognizing whether a given vertex of T is a Banks winner is NP-complete, the computation of a Banks winner of T is polynomial, and more precisely linear with respect to the size of T.
