January 12, 1997: Java applets that solve puzzles automatically
(Tokyo,Japan)
From this page, you can follow pages that contains Java applets with which you can observe automatic and rapid processes of finding magic squares, coloring the USA map, solvingthe N queens problem (a problem to find a layout of queens on N x N ``chess board''),and sorting. These applets use a method called CCM that was developed by the author. You can see a different solution every time you run the applet, because random numbers are used. You can also change several parameter values and enjoy seeing that the computer is struggling hard because it looses the power of finding solutions. If you are interested in the mechanism, follow the link of CCM.
