PolycraftRLComponent

public PolycraftRLComponent()

Method Details

parseArgs

protected void parseArgs(org.apache.commons.cli.CommandLine cmdLine)

Description copied from class: DiarcComponent

Called directly after construction to pass runtime values that will override default values. This should parse all the options that additionalUsageInfo provides.zs

Overrides:

parseArgs in class DiarcComponent

additionalUsageInfo

protected List<org.apache.commons.cli.Option> additionalUsageInfo()

Description copied from class: DiarcComponent

Command line options available in sub-class. This should be paired with a parseArgs implementation.

Overrides:

additionalUsageInfo in class DiarcComponent

Returns:

init

public void init()

Description copied from class: DiarcComponent

Perform any component initialization. This should not be used for setting local fields to default values as was the case in DIARC. This method is called after the constructor, and after parseArgs. Setting default values should be done in field declaration or in the constructor.

Overrides:

init in class DiarcComponent

collectOriginalActionSet

public void collectOriginalActionSet()

initializeRL

public String initializeRL(String failedAction)

executeRL

public String executeRL(String failedAction,
 String lastAction,
 boolean actionResult)

getState

public PolycraftRLComponent.GameState getState(String failedAction,
 String action,
 boolean actionResult)

setGameOver

public void setGameOver(boolean goalAchieved)

Notify RL when a game is over, and also set isGameOver flag to exit out of local RL execution loop.

Parameters:

goalAchieved -

executeRL

public Justification executeRL(Symbol actor,
 Predicate brokenActionPredicate,
 Symbol brokenActionStatus,
 Predicate failurePredicate)

Main RL entry point for DIARC.

NOTE: this should ALWAYS return a TRUE justification to indicate that RL was successfully attempted. Otherwise, goal recovery can enter infinitely nested RL episodes (i.e., executeRL(executeRL(exuteRL(...))).
