I'm not OP, but work with MIP solvers. Yes, there is a massive difference between the commercial (CPLEX, GUROBI, and maybe XPRESS) versus the best open source solvers (CBC/CLP and GLPK). My industry can only use the open source solvers for prototyping small models and could never use one for production with the size models we have. The commercial solvers are extremely expensive too. |
