... result of Kannan, Tetali and Vempala to com- pletely solve, via a simple proof, the problem of random generation of a labeled tournament 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 n scores, there can be an exponential (in n...

... is the game of matrix nim found in Holladay (1958). In this game, call it N n ,thereisanm×n rectangular board of piles of counters. A move consists of either (1) removing any number of counters ... consists of removing any number of contiguous counters in an arbitrary line. In the game of Shrage (1985), a position consists of a finite number of rectangles of integer sides...

... degree of x i is 2, and the degree of a 0 is ∆ − 1. However, the degree of a 1 isthesameinbothtrees,soS wins either by Rule 2 or by Rule 3.  Since P is a maximum path in G, no point of V −P ... sum of the degrees of the vertices in such a set is exactly n − 1. However, when three or more of the cliques have two or more points, the graph does not have a spanning caterpilla...
