YASS offers two independent features:
* Search for solutions of Sokoban puzzles.
* Search for improvements of existing solutions.
Solving and optimizing Sokoban puzzles are complicated tasks for a computer program, so the program can only handle small puzzles.
YASS for Android can integrate with any Sokoban clone that supports solver plug-ins, like Soko++ or BoxMan.
YASS for Android is based on YASS for Windows and other operating systems made by Brian Damgaard. See the official download page:
