We present an update operation, syntactic update, based on Winslett's Possible Models Approach (PMA). The PMA receives a set of propositional formulas describing a situation of the world, and a set of formulas describing the postconditions of an action, and determines the set of models describing the possible states of the world after the execution of the action. In this paper we describe a way of...
Planning problems, in which a sequence of actions are sought to go from a given state to a desired final state, or goal, have traditionally been hard to handle computationally. In particular and in the most usual case, the goal is not just to find a satisfying plan, but rather to find the best one. Searching for such optimum, i.e. shortest, plan, increases complexity even further. Frequently, specialised...
This work is based on the multimodal logic L(MQ), recently introduced, which formalizes order-of-magnitude qualitative reasoning. The aim of this paper is to provide a sound and complete tableau method for the future fragment of L(MQ).
