Toward Understanding Variable Ordering Heuristics for Constraint Satisfaction Problems
Most previous work on understanding variable ordering heuristics for constraint satisfaction problems has focused on the ability to recover from bad decisions. It has been demonstrated however that this ability cannot be the full explanation of the quality of a variable ordering heuristic [8]. In this paper, we develop a more complete framework for analyzing heuristics based on optimal policies...
متن کاملUsing SAT Encodings to Drive CSP Value Ordering Heuristics
In this paper, we address the issue of designing from SAT new value ordering heuristics for CSP. We show that using the direct and support SAT encodings of CSP instances, such heuristics can be naturally derived from the well-known two-sided Jeroslow-Wang heuristic. These heuristics exploit the bi-directionality of constraint supports to give a more comprehensive picture in terms of domain redu...
متن کاملEffect of DisCSP Variable-Ordering Heuristics in Scale-Free Networks
A Distributed Constraint Satisfaction Problem (DisCSP) is a constraint satisfaction problem in which variables and constraints are distributed among multiple agents. Various algorithms for solving DisCSPs have been developed, which are intended for general purposes, i.e., they can be applied to any network structure. However, if a network has some particular structure, e.g., the network structu...
متن کاملOn Conflict-driven variable ordering heuristics
It is well known that the order in which variables are instantiated by a backtracking search algorithm can make an enormous difference to the search effort in solving CSPs. Among the plethora of heuristics that have been proposed in the literature to efficiently order variables during search, a significant recently proposed class uses the learning-from-failure approach. Prime examples of such h...
متن کاملHeuristics Guided by the Quality of solutions in Weighted CSP
Weighted Constraint Satisfaction Problems (WCSP) are used to model and to solve some constraint optimization problems. WCSPs are often solved by complete or partial tree search strategies combined with filtering. For these methods, variable ordering heuristic (MinDom/FutDeg) and value ordering heuristic (MinAC) are considered to be the most efficient ones. In this paper, we propose a new value ...
