I’ve already tested solving the mps model with Gurobi and it does so really well. Status quo in Sage: Frontend class MixedIntegerLinearProgram. PuLP can then call any of numerous external LP solvers (CBC, GLPK, CPLEX, Gurobi etc) to solve this model and then use python commands to manipulate and display the solution. On Debian or Ubuntu, installing PuLP is relatively easy: $ sudo pip install pulp # PuLP $ sudo apt-get install glpk-utils # GLPK $ sudo apt-get install coinor-cbc # CoinOR. Ralphs (Lehigh University) Open Source Optimization August 21, 2017 Motivated by wanting to learn python and by reading the Wikipedia article on bin packing (it's a fascinating topic, really), I decided to spend an evening building a Bin Packing solver using Python.
