Implementations are available in the repository linked to from the article. Not quite "ready for production", but hopefully a useful starting point. https://github.com/matslina/bfoptimization
Here is the code to convert BF to C, in case anyone else is interested https://gist.github.com/primaryobjects/0ba06f1f6f0d3e984d89
Here it is running the converted C code https://ideone.com/z16KPJ
Very cool.
