Class ConstantWorldGenerator

java.lang.Object

burlap.oomdp.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.

Constructor Detail

ConstantWorldGenerator

@Deprecated
public ConstantWorldGenerator(SGDomain domain,
                                 JointActionModel jam,
                                 JointReward jr,
                                 TerminalFunction tf,
                                 SGStateGenerator sg)

Deprecated.

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

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,
                      JointReward jr,
                      TerminalFunction tf,
                      SGStateGenerator 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,
                                 JointActionModel jam,
                                 JointReward jr,
                                 TerminalFunction tf,
                                 SGStateGenerator sg,
                                 StateAbstraction abstractionForAgents)

Deprecated.

This constructor is deprecated, because SGDomain objects are now expected to have a JointActionModel associated with them, making the constructor parameter for it unnecessary. Instead use the constructor ConstantWorldGenerator(burlap.oomdp.stochasticgames.SGDomain, burlap.oomdp.stochasticgames.JointReward, burlap.oomdp.core.TerminalFunction, burlap.oomdp.stochasticgames.SGStateGenerator, burlap.oomdp.auxiliary.StateAbstraction)

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,
                      JointReward jr,
                      TerminalFunction tf,
                      SGStateGenerator sg,
                      StateAbstraction 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
