This paper presents
open-wbo
, a new MaxSAT solver.
open-wbo
has two main features. First, it is an open-source solver that can be easily modified and extended. Most MaxSAT solvers are not available in open-source, making it hard to extend and improve current MaxSAT algorithms. Second,
open-wbo
may use any MiniSAT-like solver as the underlying SAT solver. As many other MaxSAT solvers,
open-wbo
relies on successive calls to a SAT solver. Even though new techniques are proposed for SAT solvers every year, for many MaxSAT solvers it is hard to change the underlying SAT solver. With
open-wbo
, advances in SAT technology will result in a free improvement in the performance of the solver. In addition, the paper uses
open-wbo
to evaluate the impact of using different SAT solvers in the performance of MaxSAT algorithms.
