A tournament is an oriented digraph in which every pair of vertices is joined by an arc. An in-tournament digraph is a digraph in which the set of in-neighbours of each vertex induces a tournament. This note gives an \(O(m+n\log n)\) algorithm for finding a longest path and cycle in an in- tournament digraph, where \(m\) and \(n\) are the numbers of arcs respectively vertices of the in-tournament digraph.
