... result of Kannan, Tetali and Vempala to com-pletely solve, via a simple proof, the problem of random generation of a labeledtournament with a given score vector. The proof uses the method of path ... score vector of a tournament is the sequence of out-degrees of the vertices of the tournament. In general, given a score vector with nscores, there can be an exponential (in n) number of labeled ... sequence of ∆-reversals.Proof. The key observation is that two different tournaments sharing the samescore vector differ in the orientation of an edge-disjoint collection of cycles. The proofwill...
