RAIN.GOB.GOBTree.GOBGoalNode Class Reference

GOBGoalNode represents high level goals in Goal Oriented Behavior (GOB). These goals may not be tied directly to actions (i.e., not 1 to 1) but instead represent preferrable world states. GOBGoals have insistence functions that produce a "discomfort level", which can be translated to the urgency to which the goal requires satisfaction. GOB operates by choosing choosing actions which are predicted to do the best job of reducing overall discomfort/urgency. More...
