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...
We consider the class of finite-state programs executed by an unbounded number of replicated threads communicating via shared variables. The thread-state reachability problem for t...
We prove that any finite set of half-planes can be colored by two colors so that every point of the plane, which belongs to at least three half-planes in the set, is covered by ha...
In our problem we are given a set of customers, their positions on the plane and their demands. Geometrically, the area covered by a directional antenna with parameters , ,
