How to extract negative information from programs is an important issue in logic programming. Here we address the problem for functional logic programs, from a proof-theoretic pers...
A calculus for developing programs from specifications written as predicates that describe the relationship between the initial and final state is proposed. Such specifications are...
Abstract. An overview of the concept of program similarity is presented. It divides similarity into two types--syntactic and semantic-and provides a review of eight categories of m...

We are interested in semantical underpinnings for existing approaches to preference handling in extended logic programming (within the framework of answer set programming). As a s...
Focus in the paper is on the definition of linear bilevel programming problems, the existence of optimal solutions and necessary as well as sufficient optimality conditions. In th...
