MiniZinc is just a modeling language, you can throw the problem at different solvers. You can use SAT solvers (assuming you have some wrapper that translates FlatZinc to CNF), CP solvers (can be SAT-based underneath or use different algorithms like MAC), SMT solvers (SAT Modulo Theories like Arithmetic), MIP solvers (usually Simplex + Branch & Bound)...
