Let P be a set of n points in general position in the plane. Let Xk(P ) denote the number of empty convex k-gons determined by P. We derive, using elementary proof techniques, sev...
Recent work on combining CSP and B has provided ways of describing systems comprised of components described in both B (to express requirements on state) and CSP (to express intera...
We show how a polynomial-time prover can commit to an arbitrary finite set Ë of strings so that, later on, he can, for any string Ü, reveal with a proof whether Ü ¾ Ë or Ü ...
Levesque introduced the notion of only-knowing to precisely capture the beliefs of a knowledge base. He also showed how only-knowing can be used to formalize non-monotonic behavio...
Abstract. Component software means reuse and separate marketing of pre-manufactured binary components. This requires components from different vendors to be composed very late, pos...
