`JuLS` is a Julia Local Search solver that combines Constraint Based Local Search (CBLS) and Constraint Programming (CP) to solve Constraint Optimization Problem (COP).

A paper with theoretical foundations accompanying this solver can be found [here](JuLS.pdf). The CBLS part is inspired by the paper [LocalSolver 1.x](https://www.afpc-asso.org/assets/actes/actes-JFPC-2011.pdf#page=37).
