This app is designed to find the best way to pair players in a round-robin tournament. It maximizes the number of games being played simultaneously. It does this by representing the current state of the tournament as a graph with players as nodes and unplayed games as edges, and uses Edmonds' Blossom Algorithm to find the maximum cardinality matching over this graph.
