Ricochet Robot February 2012
Implementation of a board game called Ricochet Robot including a GUI and a very fast solver.
My friend introduced me to a board game called Ricochet Robot (or Rasende Roboter in its original German form). It's a fun game, but I found it even more fun as a programming problem. I implemented the game in Python, including a user interface and a solver. After that, I sped up the solver tremendously by porting it to C. My solver includes several "tricks" that make it quite fast. See these slides for more details.
