Daily fantasy optimizer, built on Google's or-tools
Currently, the Python bindings for or-tools are not easy to install, so that is left as an exercise for the reader :)
Initial inspiration and data model: http://www.barelyknown.com/blog/2014/11/13/d6q2mihtpbtehi3u6sh7z8vc7rnr4f
Linear constraint-based daily fantasy lineup optimizer, with support for position limits, flex spots, and lock/ban. Generates top N lineups, with support for number of unique players per lineup. Fast (sub-second computations).
optimize_cfb.py has the most features :)
