Abstract: The paper addresses the problem of computing siphons and traps in a standard Petri net. In particular, starting from a clear formulation in terms of predicate logic, it is shown how binary ...

Abstract: Inductive logic programming (ILP) is a research area which has its roots in inductive machine learning and computational logic. The paper gives an introduction to this area based on a ...

Predicate logic is an extension of propositional logic. Here we consider what is called first-order predicate logic, abbreviated FOL (sometimes abbreviated PL1, not to be confused with the programming ...

We say that an n-argument predicate $P\subset \Omega ^{n}$ is finite, if P is a finite set. Note that the set of individuals Ω is infinite! Finite predicates are ...

Knowledge representation and reasoning in logic programming constitute a core area of artificial intelligence that formalises how information is symbolically encoded and manipulated. This field ...
