September release of or-tools
I just released or-tools version 6.4. The biggest change is that I reverted the ortools-<linux distro> specific pypi modules as we now have manylinux distro agnostic wheel files. Here is the full change log: Change in platforms Pypi modules on Linux platforms are now delivered as wheel files using the manylinux1 tag. Thanks to Federico Ficarelli. With this change, we have backtracked the per-linux modules introduced in the July 2017 release. New features Improved scaling method used inside GLOP. Fix wrapping of evaluators in the C# routing library. Thanks to DevNamedZed. Improve the performance of the flatzinc presolve for large models. Use the SAT backed for flatzinc by default. Improve performance of the Core based approach for the sat solver. Fix bug in the linear assignment algorithm that was failing incorrectly. Added F# examples in ortools/examples/fsharp. (Thanks to Matthew Moore). Remove check for positive penalties in the routing library.
