Philosophy of the MiniZinc challenge
MiniZinc arose as a response to the extended discussion at CP2006 of the need for a standard modelling language for CP. This is a challenging problem, and we believe MiniZinc makes...

Some Progress in Satisfiability Checking for Difference Logic
Abstract. In this paper we report a new SAT solver for difference logic, a propositional logic enriched with timing constraints. The main novelty of our solver is a tighter integra...

Variable neighborhood search and local branching
In this paper we develop a variable neighborhood search (VNS) heuristic for solving mixed-integer programs (MIPs). It uses CPLEX, the general-purpose MIP solver, as a black-box. N...

A Minimal Extension of the WAM for clp(FD)
nt an abstract instruction set for a constraint solver over finite domains, which can be smoothly integrated in the WAM architecture. It is based on the use of a single primitive...

Equivalence Checking Combining a Structural SAT-Solver, BDDs, and Simulation
This paper presents a verification technique for functional comparison of large combinational circuits using a novel combination of known approaches. The idea is based on a tight...
