Lookahead Saturation with Restriction for SAT
We present a new and more efficient heuristic by restricting lookahead saturation (LAS) with NVO (neighbourhood variable ordering) and DEW (dynamic equality weighting). We report o...

Solving Over-Constrained Problems with SAT
Abstract. We present a new generic problem solving approach for overconstrained problems based on Max-SAT. We first define a clausal form formalism that deals with blocks of clau...

An Algorithm for SAT Without an Extraction Phase
An algorithm that could be implemented at a molecular level for solving the satisfiability of Boolean expressions is presented. This algorithm, based on properties of specific se...

On Solving Soft Temporal Constraints Using SAT Techniques
In this paper, we present an algorithm for finding utilitarian optimal solutions to Simple and Disjunctive Temporal Problems with Preferences (STPPs and DTPPs) based on Benders’...

Observed Lower Bounds for Random 3-SAT Phase Transition Density Using Linear Programming
We introduce two incomplete polynomial time algorithms to solve satisfiability problems which both use Linear Programming (LP) techniques. First, the FlipFlop LP attempts to simul...
