A Constraint-Based Language for Virtual Agents. In order to describe agent behaviors, we have designed VRCC, a concurrent constraint programming language integrated in the VRML environment. The basis of this declarative language is the notion of constraint, and it is based on the Timed Concurrent Constraint framework, which integrates a discret

Constraint (Logic) Programming: A Survey on Research and ApplicationsProgramming Languages, and has to do with modeling, solving, and programming real-life problems which can be described as a set of statements (the .) which describe some relationship between the problem’s variables. This survey paper gives a brief introduction to C(L)P, presents a (necessarily parti

Some Remarks on Boolean Constraint Propagationtablish a completeness result. Then we show an equivalence in an appropriate sense between Boolean constraint propagation and unit propagation, a form of resolution for propositional logic..Subsequently we characterize one set of such rules by means of the notion of hyper-arc consistency introduced

Abstracting Soft Constraints problem can help us in many ways: for example, to find good approximations of the optimal solutions, or also to provide us with information that can make the subsequent search for the best solution easier. The results of this paper show that the proposed scheme is promising; thus they can be used a

Decomposable Constraintsinality” constraints. Certain classes of these non-binary constraints are “network decomposable” as they can be represented by binary constraints on the same set of variables. We compare theoretically the levels of consistency which are achieved on non-binary constraints to those achieved on their b
