Solution Equivalent Subquadrangle Reformulations of Constraint Satisfaction Problems
Abstract. Subquadrangles are a natural way in which to represent constraints as they do not restrict any subset of their scope. There are already known methods for converting any g...

Unbiased Statistics of a Constraint Satisfaction Problem - a Controlled-Bias Generator
: We show that estimating the complexity (mean and distribution) of the instances of a fixed size Constraint Satisfaction Problem (CSP) can be very hard. We deal with the main two ...

Heavy-Tailed Phenomena in Satisfiability and Constraint Satisfaction Problems
We study the runtime distributions of backtrack procedures for propositional satisfiability and constraint satisfaction. Such procedures often exhibit a large variability in perfor...
