Abstract—Localization, which is the determination of one’s location in a known terrain, is a fundamental task for autonomous robots. This paper presents several new basic theor...
Abstract. We consider the problem of verifying the safety of wellstructured transition systems (WSTS) with auxiliary storage. WSTSs with storage are automata that have (possibly) i...
Decision making, whether by an individual or a group, can be substantially enhanced by a "systems thinking" approach. Because groups are often challenged to justify thei...
⎯A new nonslicing floorplan representation, the moving block sequence (MBS), is proposed in this paper. Our idea of the MBS originates from the observation that placing blocks on...
