Hello, It seems logical that a random state scrambler be used for the 2x2, similar to CubeExplorer for the 3x3. After all, the 2x2 is a very simple puzzle (for a computer) and can be solved optimally in 11 moves (according to Jaap's page). Recently, I decided to write a 2x2 solver with this function in mind. I finished the program, and I would like to propose that the WCA switch to this method of scrambling. The main benefit, I believe, is efficiency. The average 2x2 position can be solved in 8.76 face turns. We are currently using 25 moves, this seems excessive. This method of scrambling also guarantees as uniform a distribution as Java's random generator will allow. The URL of the scrambler is [url:pq1nzqod]http://www.rubikscubing.com/2x2Scramble.jar[/url:pq1nzqod]. Feel free to make any comments or criticisms; I will do my best to address them. I have not tested this on anything but Windows; I believe it should work, but let me know if it doesn't. Tim Reynolds

Hi Tim, Good idea and good work. Would it be possible for you to transfer your program from Java to Javascript? Actually, to embed it in Jaap's script? Thanks, Ron

Hi Ron, Sure, I'll start working on that as soon as I get a chance (probably not until about Sunday though). Tim

Java's Random class is sometimes very bad, producing patterns it really shouldn't. If I remember correctly, the SecureRandom class is much better. Don't know about JavaScript, but I recommend exploring this issue.
