One can reduce the problem of proving that a polynomial is nonnegative, or more generally of proving that a system of polynomial inequalities has no solutions, to finding polynomi...
Hypergraphs are a very powerful tool and can represent many problems. In this paper we define a new image representation based on hypergraphs. This representation conducts to a n...
Robertson and Seymour (1990) proved that graphs of bounded tree-width are well-quasi-ordered by the graph minor relation. By extending their arguments, Geelen, Gerards, and Whittle...
We develop and prove sound a concurrent separation logic for a language with Pthreads-style barriers. Although Pthreads barriers are widely used in systems, and separation logic is...
Abstract—Triangulation serves as the basis for many geometrybased algorithms in wireless sensor networks. In this paper we propose a distributed algorithm that produces a triangu...
