The ability of a planner to modify a plan is considered as a valuable tool for improving ee-ciency of planning by avoiding the repetition of the same planning eeort. From a computational complexity point of view, however, it is by no means obvious that modifying a plan is com-putationally as easy as planning from scratch if the modiication has to follow the principle of \conservatism," i.e., to...
