This repository contains the source code for solving the 15-Hole Peg Soltaire game in a number of different programming languages. It is based off the code that Jonathan Fuerth wrote for his presentation on Java/HotSpot performance. You will find that presentation here.
Of course there are caveats. The C code provided follows an Object Oriented style. It is certainly possible to optimize this code further using a more procedural style with less memory allocation. But then this style of coding should be adapted to the other languages presented as well. Further more I'd argue that maintaining code written in this manneris difficult and expensive. Regardless, I whole heartedly encourge you submit pull requests with these new versions in separate directories based on the style/technique used.
