Hi, It's a shot in the dark as I am dubious I will get an answer. However, I have tried to compile PyLPSolve on Windows 64 bit, Python 2.7 64...

only 2 minor changes: 1) change print statement to function; 2) use dict.items under py3, which is dict.iteritems under py2

lpsolve supports ILP, but I didn't see anywhere on the PyLPSolve user guide how to invoke it...

Add Python 3 support

Seems to work fine! ``` python In [1]: import pylpsolve as lp In [2]: model = lp.LP() In [5]: model.addConstraint([[1, 0], [0, 1], [1, -1], [-1, -1]], '>=', [0, 0,...

Provides support for the `timeout` parameter. The `timeout` parameter is the positive integer seconds before either returning the optimal result or raising a timeout error. The parameter defaults as `0`,...

LPSolve doesn't support strict inequality, and it's extremely surprising to successfully add a constraint like `lp.addConstraint({'x': 1}, '>', 0)` and have it behave silently off-by-one. I believe it's a design...

Raise specific error exception types.

This enables more easily catching specific conditions like suboptimal solution.

Read solved variables with get_var_primalresult to avoid incorrect column indices after presolve.

1

This fixes use of incorrect column indices when the presolver removes rows or columns. A serious but silent error when using `presolve_cols`.

My editor was going nuts with all of the trailing whitespace (trimming it all automatically which munged up the diffs). Easy to fix once, though.

This lets `printLP` print the actual column names used in the constraints.
