A tournament is a complete directed graph, for each pair of vertices x, y either (x, y) is an arc or
(y, x) is an arc. One can think of this as a round robin tournament, where the vertices represent
teams, each pair plays exactly once, with the direction of the arc indicating which team wins.
(a) Prove that every tournament has a direct Hamiltonian path. That is a labeling of the teams
V1, V2,..., Un so that vi beats Vi+1. That is a labeling so that team 1 beats team 2, team 2
beats team 3, etc.
(b) A digraph is strongly connected if there is a directed path from any vertex to any other
vertex. Equivalently, there is no partition of the teams into groups A, B so that every team
in A beats every team in B. Prove that every strongly connected tournament has a directed
Hamiltonian cycle. Use this to show that for any team there is an ordering as in part (a) for
which the given team is first.
(c) A king in a tournament is a vertex such that there is a direct path of length at most 2 to
any…
The following is known. The complete graph K2t on an even number of vertices has a 1-
factorization (equivalently, its edges can be colored with 2t - 1 colors so that the edges incident
to each vertex are distinct). This implies that the complete graph K2t+1 on an odd number of
vertices has a factorization into copies of tK2 + K₁ (a matching plus an isolated vertex).
A group of 10 people wants to set up a 45 week tennis schedule playing doubles, each week, the
players will form 5 pairs. One of the pairs will not play, the other 4 pairs will each play one
doubles match, two of the pairs playing each other and the other two pairs playing each other.
Set up a schedule with the following constraints: Each pair of players is a doubles team exactly 4
times; during those 4 matches they see each other player exactly once; no two doubles teams play
each other more than once.
(a) Find a schedule. Hint - think about breaking the 45 weeks into 9 blocks of 5 weeks. Use
factorizations of complete…
. The two person game of slither is played on a graph. Players 1 and 2 take turns, building a path in the graph. To start, Player 1 picks a vertex. Player 2 then picks an edge incident to the vertex. Then, starting with Player 1, players alternate turns, picking a vertex not already selected that is adjacent to one of the ends of the path created so far. The first player who cannot select a vertex loses. (This happens when all neighbors of the end vertices of the path are on the path.) Prove that Player 2 has a winning strategy if the graph has a perfect matching and Player 1 has a winning strategy if the graph does not have a perfect matching. In each case describe a strategy for the winning player that guarantees that they will always be able to select a vertex. The strategy will be based on using a maximum matching to decide the next choice, and will, for one of the cases involve using the fact that maximality means no augmenting paths. Warning, the game slither is often described…

- Let D be a directed graph, with loops allowed, for which the indegree at each vertex is at most k and the outdegree at each vertex is at most k. Prove that the arcs of D can be colored so that the arcs entering each vertex must have distinct colors and the arcs leaving each vertex have distinct colors. An arc entering a vertex may have the same color as an arc leaving it. It is probably easiest to make use of a known result about edge coloring. Think about splitting each vertex into an ‘in’ and ‘out’ part and consider what type of graph you get.arrow_forward10 20 30 y vernier protractor scales. 60 30 0 30 60 40 30 20 10 0 30 60 0 10.
