It's always great to see examples of more niche algorithms outperform the familiar stochastic/monte carlo algorithms that first come to mind when approaching a problem.

It would be nice to open up the 5 year old code and put it on github.

The code has been on GitHub for a while.

The code is neither obfuscated nor minimized, so what's not opened up about it?
