From: Structure constrained by metadata in networks of chess players
Representation of the subnetwork composed by four top-rated players in the OTB database. Each node represents a player, containing as metadata the name of the player and her/his mean Elo (with the corresponding standard deviation). If two players have met al least once, they are joined by a link. The weight and the direction of the link depends on the net flux of Elo between those players, after counting all the games they played each other. Take, as an example, players Anand and Carlsen. The existing link between them goes from Anand to Carlsen, and has a weight of 15 meaning that, after considering all the games they have played against each other, the net result was that Anand transferred 15 points of Elo to Carlsen.
