ActionLearning

public ActionLearning(StateMachine stateMachine,
 RootContext rootContext,
 boolean useGui)

Parameters:

stateMachine - state machine used to store world information

rootContext - root context which will be used to instantiate observers and simulation capability

Method Details

registerWithTRADE

public void registerWithTRADE(Collection<String> groups)

Register this class with TRADE to make its services available.

startQueuingGoals

public void startQueuingGoals()

updateActionLearning

public boolean updateActionLearning(Predicate newAction,
 Symbol status)

shouldIgnore

public boolean shouldIgnore(Goal goal)

addGoal

public void addGoal(Goal goal)

check to see if the goal should be added to the action being learned and if so add it.

Parameters:

goal - goal to add

getLearningStatus

public ActionLearningStatus getLearningStatus()

changeLearningExecution

shouldExecute

public boolean shouldExecute()

modifyAction

public void modifyAction(Predicate action,
 Predicate modification,
 Predicate location)

modifyAction(actor,action, modification, location)

Parameters:

action - : predicate containing action and arguments: arguments are required for grounding of new action/goal onto learning state actionName(actor, arg0, arg1, ... argN) predicate containing new action predicate and old task predicate like(newAction(arg0, arg1 ... argN), existingAction(arg0, arg1 ... argN)

modification - : information regarding the modification to make : type(actionStep, actionStep) : type(actionStep) : type(type, type) //TODO:brad is this actually valid? : type: insert, delete, replace : insert(action_predicate) : delete(action_predicate) : replace(new_action_predicate, old_action_predicate)

location - : reference in action script : relation(actionStep, actionStep) : relation(actionStep) : relation: and/before/after/condition/effect/argument : before(action_predicate) : after(action_predicate) : and(relation,relation)) : condition() : effect() : argument()
