The inequality-satisfiability problem
We define a generalized variant of the satisfiability problem (SAT) where each "clause" is an or-list of inequalities in n variables. The inequality satisfiability probl...

Another Complete Local Search Method for SAT
Local search algorithms are one of the effective methods for solving hard combinatorial problems. However, a serious problem of this approach is that the search often traps at loca...

Neighbourhood Clause Weight Redistribution in Local Search for SAT
Abstract. In recent years, dynamic local search (DLS) clause weighting algorithms have emerged as the local search state-of-the-art for solving propositional satisfiability proble...
