Member Function Documentation

◆ addObservation()

virtual bool gum::ILearningStrategy::addObservation	(	Idx	actionId,
		const Observation *	obs
	)

pure virtual

Gives to the learner a new transition.

Parameters

actionId	: the action on which the transition was made
obs	: the observed transition

Returns: true if learning this transition implies structural changes (can trigger a new planning)
