,Degreewidth: A New Parameter for Solving Problems on Tournaments,lic. The degreewidth of a tournament . denoted by . is the minimum value . for which we can find an ordering . of the vertices of . such that every vertex is incident to at most . backward arcs (. an arc . such that .). Thus, a tournament is acyclic if and only if its degreewidth is zero. Additional
