BCP provides the user with an object-oriented framework that can be used to develop an efficient problem class specific MIP solver without all the implementational effort. By default BONMIN uses Cbc to solve them, but it can also be set up to use the commercial solver Cplex4. If the solver is not on the path, the full path to the solver will need to be passed in. What are the risks of using open source solvers (GLPK, BONMIN, COIN-OR, etc) instead of Gurobi or CPLEX? Being new to the OR world and coming mostly from the ML world, I'm inclined to assume that there is a free open source toolkit for just about everything, given the success of tools like Scikit-learn, Pandas, Tensorflow, etc. In Section 4, we describe the capabilities of our MINLP solver Bonmin (Basic Open-source Nonlinear Mixed INteger programming) and how we constructed it using other components of COIN-OR.
