One of the critical problems in the call center industries is the staffing problem since they must face variable demands and because staff costs represent a major part of the cost...
Abstract. We examine the maintenance of data consistency in the presence of application-database interactions. Currently, a programmer must insert explicit checks to ensure that da...
In this paper we show how Constraint Programming (CP) techniques can improve the efficiency and applicability of grid-based algorithms for optimising surface contact between comple...
The subgraph isomorphism problem consists in deciding if there exists a copy of a pattern graph in a target graph. We introduce in this paper a global constraint and an associated ...
We define the semantics of logic programs with (abstract) constraint atoms in a way closely tied to default logic. Like default logic, formulas in rules are evaluated using the cl...
