The Virtuality of Constraints and the Constraints of Virtuality
Constraints, 1996We propose to extend current Constraint Logic Programming techniques and to export them from their classical Logic Programming setting to more conventional and widely used paradigms, such as the Java language. We also advocate for the use of constraints in new types of applications such as 3D graphics and Virtual Reality systems.

Constraints and Constraint Solving: An Introduction
2001The central idea of constraints is to compute with descriptions of data instead of to compute with data items. Generally speaking, a constraint-based computation mechanism (in a broad sense, this includes for instance deduction calculi and grammar formalisms) can be seen as a two-tired architecture, consisting of A language of data descriptions ...

In digital storage systems where the input to the noisy channel is required to satisfy a modulation constraint, the constrained code and error-control code (ECC) are typically designed and decoded independently. The achievable rate for this situation is evaluated as the rate of average intersection of the constraint and the ECC.

A Global Constraint Combining a Sum Constraint and Difference Constraints
2000This paper introduces a new method to prune the domains of the variables in constrained optimization problems where the objective function is defined by a sum y = Σxi, and where variables xi are subject to difference constraints of the form xj - xi ≤ c.

Set constraints: A pearl in research on constraints
1997The topic of set constraints is a pearl among the research topics on constraints. It combines theoretical investigations (ranging from logical expressiveness, decidability, algorithms and complexity analysis to program semantics and domain theory) with practical experiments in building systems for program analysis, addressing questions like ...

The aim of an identification result for a linearly constrained problem is to show that if the sequence generated by an optimization algorithm converges to a stationary point, then there is a nontrivial face \(F\) of the feasible set such that after a finite number of iterations, the iterates enter and remain in the face \(F\).

Constraints, 1996
Recently, interest in constraints and databases has increased significantly as the databases field has started to consider broader application domains. In this short position statement, I identify some of the most promising direcrtions, in my opinion, for the use of constraints in the context of databaes management systems.

Spacetime constraints are a new method for creating character animation. The animator specifies what the character has to do, for instance, "jump from here to there, clearing a hurdle in between;" how the motion should be performed, for instance "don't waste energy," or "come down hard enough

A surrogate constraint is an inequality implied by the constraints of an integer program, and designed to capture useful information that cannot be extracted from the parent constraints individually but is nevertheless a consequence of their conjunction.
