Search in planning involves simulating various see whether or not they will desired situation. Since space possible quite large comparison with set that actually situation, it important carefully guide search. At each point process, planner should have before a representation describes planner's intentions and their potential consequences help deciding how refine those intentions. This essence what has been called hierarchical planning. The result decision constitutes commitment on part planner, as commitments are made during form basis for subsequent decisions. In most situations, impossible guarantee decision, once made, immune retraction. sort routine situations we concerned with, retracting previous commitments, backtracking commonly referred to, while can't avoided altogether, controlled. One can, direct making so that, having performed amount search (significantly less than required entire problem), one reliably commit particular without fear later paper architecture supports well suited applications involving deadlines, travel time, resource considerations.
