In this paper we extend the Revision Programming framework--a logic-based framework to express and maintain constraints on knowledge bases-with different forms of preferences. Pref...
Many optimisation problems contain substructures involving constraints on sequences of decision variables. Such constraints can be very complex to express with mixed integer progra...
The heterogeneity of architectural constraint languages makes difficult the transformation of architectural constraints throughout the development process. Indeed they have signiï...
Abstract. We present a new constraint system called INES. Its constraints are conjunctions of inclusions t1 t2 between rst-order terms (without set operators) which are interpreted...
This paper2 details the stages of building a substantial, carefully specified, fully tested and fully operational university and school timetabling system. This is reported as a c...
