Replanning in RALPH-MEA

Replanning in RALPH-MEA

RALPH's replanning ability arises from the replanning architecture. The current enviromental situation is consistently monitored to determine when replanning has utility. Then the current plan is examined, and promising parts of the plan are selected. The replanning region is recursively narrowed until either all parts of the plan have negative replanning value, or a decision node is modified to maximize utility.
