Python tools for Modeling and Solving Mixed-Integer Programs

Python MIP (Mixed-Integer Linear Programming) Tools

Python MIP is a collection of Python tools for the modelling and solution of Mixed-Integer Linear programs (MIPs). MIP syntax was inspired by Pulp and the Gurobi Python API. Porting Pulp and Gurobi models should be quite easy.

Some of the main features of MIP are:

• high level modelling: write your MIP models in Python as easily as in high level languages such as MathProg: with operator overloading you can easily write linear expressions in Python;

• multi solver: works with different MIP solvers; right now the commercial Gurobi solver and the open source COIN-OR Branch-&-Cut CBC solver are supported;

• fast: the Python MIP package calls directly the native dynamic loadable library of the installed solver using the modern python ctypes module; models are efficiently stored and optimized by the solver and MIP transparently handles all communication with your Python code;

• completely written in modern statically typed Python 3;

• solution pool: query the elite set of solutions found during the search;

• mipstart: use a problem dependent heuristic to generate initial feasible solutions for the MIP search;

• cut generation: write your cut generator in python and integrate it into the Branch-and-Cut search (currently only for Gurobi).
