Local consistency for extended CSPs
We extend the framework of Constraint Satisfaction Problems to make it more suitable for/applicable to modern constraint programming languages where both constraint satisfaction and constraint solving have a role. Some rough principles for local consistency conditions in the extended framework are developed, appropriate notions of local consistency are formulated, and relationships between the ...
متن کاملMaintaining Global Hull Consistency with Local Search for Continuous CSPs
This paper addresses constraint solving over continuous domains in the context of decision making, and discusses the trade-off between precision in the definition of the solution space and the computational efforts required. In alternative to local consistency, we propose maintaining global hull-consistency and present experimental results that show that this may be an appropriate alternative t...
متن کاملA Parameterized Local Consistency for Redundant Modeling in Weighted CSPs
The weighted constraint satisfaction problem (WCSP) framework is a soft constraint framework which can model many real life optimization or overconstrained problems. While there are many local consistency notions available to speed up WCSP solving, in this paper, we investigate how to effectively combine and channel mutually redundant WCSP models to increase constraint propagation. This success...
متن کاملArc Consistency for Dynamic CSPs
Constraint Satisfaction problems (CSPs) are a fundamental concept used in many real world applications such as interpreting a visual image, laying out a silicon chip, frequency assignment, scheduling, planning and molecular biology. A main challenge when designing a CSP-based system is the ability to deal with constraints in a dynamic and evolutive environment. We talk then about on line CSP-ba...
متن کاملConsistency Techniques for Numeric CSPs
Many problems can be expressed in terms of a numeric constraint satisfaction problem over finite or continuous domains (numeric CSP). The purpose of this paper is to show that the consistency techniques that have been developed for CSPs can be adapted to numeric CSPs. Since the numeric domains are ordered the underlying idea is to handle domains only by their bounds. The semantics that have bee...
