23 is everywhere! - Greg FunchessMr. 23Tumblr (3.0; @mr23)http://mr23.g23.co/Hi! <br /> I've been busy lately building a digitalized version of Rubik's Cube in Matlab. Up untill now, I mainly worked on the appearance and interactibility of the program, but ofcourse I want to solve it eventually...or rather let it solve itself. Since I don't know anything about solving Rubik's cube, I thought of writing a genetic algorithm. When I googled this to see if anyone had ever thought of this before (which ofcourse was the case), I came across your blog. Unfortunately you haven't posted anything about this problem after March 2010, so I was wondering if you ever came up with an effective algorithm. Mine is able to come halfway in solving the cube, but after that, almost every sequence of moves destroys the relatively 'fit' state it was in. Are you interested in the algorithms I'm using (evolution, fitness-function)? I would love to hear your thoughts on this subject! <br /> <br /> Kindest regards,<br /> <br /> JorenHello, yeah unfortunately I didn’t bother implementing this. I was going to and at the time it...http://mr23.g23.co/post/5373012517http://mr23.g23.co/post/5373012517Tue, 10 May 2011 17:58:52 -0500Collatz Color (my art project for today)<img src="http://24.media.tumblr.com/tumblr_lke7wq1JJJ1qavtc4o1_400.png"/><br/><br/><p>Collatz Color (my art project for today)</p>http://mr23.g23.co/post/5030894965http://mr23.g23.co/post/5030894965Thu, 28 Apr 2011 21:50:50 -0500Sudoku Solver / GeneratorYesterday I wrote a simple Sudoku solver.
