A Meta-CSP Model for Optimal Planning
One approach to optimal planning is to first start with a sub- optimal solution as a seed plan, and then iteratively search for shorter plans. This approach inevitably leads to an...

Improved algorithms for 3-coloring, 3-edge-coloring, and constraint satisfaction
We consider worst case time bounds for NP-complete problems including 3-SAT, 3-coloring, 3-edge-coloring, and 3list-coloring. Our algorithms are based on a constraint satisfaction...

GAC on Conjunctions of Constraints
Abstract. Applying GAC on conjunctions of constraints can lead to more powerful pruning [1]. We show that there exists a simple heuristic for deciding which constraints might be us...

Feasible distributed CSP models for scheduling problems
Nowadays, many real problems can be formalized as Distributed CSPs. A distributed constraint satisfaction problem (DisCSP) is a CSP in which variables and constraints are distribu...
