Chess
These are results of chess games. Each node is a chess player, and a directed
edge represents a game, with the white player having an outgoing edge and the
black player having an ingoing edge. The weight of the edge represents the
outcome (+1 white won, 0 draw, −1 black won). The dataset is anonymous: the
identity of the players is unknown, and timestamps are approximate. Timestamps
are given to a one month precision, and may have been shifted towards the
future by an unknown amount.
