Class Tournament

java.lang.Object

burlap.mdp.stochasticgames.tournament.Tournament

public class Tournament
extends java.lang.Object

This class is designed to run tournaments of sets of users. It is particularly useful when there are a large number of agents whose performance is going to be compared in games in which only a subset of the agents can participate at a time, for instance running a tournament of many agents in 2-player games like iterated prisoner's dilemma. The Tournament class requires a list of agents, a world generator and a match selector. The MatchSelector determines which agents will be matched up in a game, which SGAgentType role they will play as and how many matches there will be.
