Class ConstantWorldGenerator

java.lang.Object

burlap.mdp.stochasticgames.tournament.common.ConstantWorldGenerator

All Implemented Interfaces:

WorldGenerator

public class ConstantWorldGenerator
extends java.lang.Object
implements WorldGenerator

A WorldGenerator that always generators the same WorldConfiguraiton. It takes the same parameters as a World constructor and simply passes them to the World Constructor when a new World needs to be generated.

ConstantWorldGenerator

@Deprecated
public ConstantWorldGenerator(SGDomain domain,
                                          JointModel jam,
                                          JointRewardFunction jr,
                                          TerminalFunction tf,
                                          StateGenerator sg)

Deprecated.

This constructor is deprecated, because SGDomain objects are now expected to have a JointModel associated with them, making the constructor parameter for it unnecessary. Instead use the constructor ConstantWorldGenerator(burlap.mdp.stochasticgames.SGDomain, JointRewardFunction, burlap.mdp.core.TerminalFunction, StateGenerator)

Parameters:

domain - the SGDomain the world will use

jam - the joint action model that specifies the transition dynamics

jr - the joint reward function

tf - the terminal function

sg - a state generator for generating initial states of a game

ConstantWorldGenerator

public ConstantWorldGenerator(SGDomain domain,
                              JointRewardFunction jr,
                              TerminalFunction tf,
                              StateGenerator sg)

Initializes the WorldGenerator.

Parameters:

domain - the SGDomain the world will use

jr - the joint reward function

tf - the terminal function

sg - a state generator for generating initial states of a game

ConstantWorldGenerator

@Deprecated
public ConstantWorldGenerator(SGDomain domain,
                                          JointModel jam,

Deprecated.

This constructor is deprecated, because SGDomain objects are now expected to have a JointModel associated with them, making the constructor parameter for it unnecessary. Instead use the constructor ConstantWorldGenerator(burlap.mdp.stochasticgames.SGDomain, JointRewardFunction, burlap.mdp.core.TerminalFunction, StateGenerator, burlap.mdp.auxiliary.StateMapping)

Parameters:

domain - the SGDomain the world will use

jam - the joint action model that specifies the transition dynamics

jr - the joint reward function

tf - the terminal function

sg - a state generator for generating initial states of a game

abstractionForAgents - the abstract state representation that agents will be provided

ConstantWorldGenerator

public ConstantWorldGenerator(SGDomain domain,
                              JointRewardFunction jr,
                              TerminalFunction tf,

                              StateMapping abstractionForAgents)

Initializes the WorldGenerator.

Parameters:

domain - the SGDomain the world will use

jr - the joint reward function

tf - the terminal function

sg - a state generator for generating initial states of a game

abstractionForAgents - the abstract state representation that agents will be provided
