An integrated graphic tool for developing and testing DLV programs

Abstract. In the last few years, significant improvements characterized state-ofthe-art Answer Set Programming (ASP) systems. It is now well accepted that their applicability is becoming more and more suited for real world applications requiring complex reasoning tasks. Among the available ASP systems, DLV recently came up with a large variety of language extensions, front-ends and variants that significantly widened its range of applicability. This paper presents an integrated development environment, customized for DLV and some of its extensions, which aims to simplify both the development-and-test process and the coupling of this ASP system with DBMSs.
