For two constraint systems (., ?) and (.′, ?′), and a concrete program . over constraint system (., ?), we define a corresponding abstract program . over (.′, ?′) such that the execution of . in (.′, ?′) performs

Emanuele Fabbro,Alessandro Mudaproblems, the built-in constraints often do not suffice. Unfortunately, new constraints defined with lookahead and forward declarations are often inefficient. In this paper, we present an efficient high-level constraint mechanism. High-level constraints are ordinary predicates with an additional con

They also offer powerful reasoning mechanisms (classification, inheritance, methods, etc.) which, applied on the current facts of a knowledge base, will deduce implicit or hypothetical facts and then increase the amount of knowledge..Fully integrating constraints into an object-b

The problem (for June 1993) consists of planning 308 different examinations on 33 half-days over 7 rooms of different capacities. A set of different and various constraints has

More recently it has been observed that individual problems which are very difficult can be found at some distance from the peak in the median cost

Knowledge about properties of the constraints can permit inferences that reduce the cost of consistency checking. Specifically, such inferences can be used to reduce the number of constraint checks required in establishing arc consistency, a

In contrast, Gaschnig‘s backmarking routine (BM) attempts to avoid performing redundant consistency checks. These two algorithms are combined to give FC-BM, an algorithm that attempts to minimise the number

Visible variables are the variables of interest from the outside, in the sense that a solution involves only them. For variable redundancy we mean that the elimination of a variable, together with all the c
