burlap.behavior.stochasticgames.agents.SetStrategySGAgent

All Implemented Interfaces:

SGAgent

public class SetStrategySGAgent
extends SGAgentBase

A class for an agent who makes decisions by following a specified strategy and does not respond to the other player's actions. The policy object that determines actions can leave the actingAgent field empty/null, because this the action(State) method will automatically replace it with whatever this agent's name is.
