You know, there has been a lot of talk about similar strings and data patterns in the executables, but this overlooks the most obvious way to tell that a program is cloned: how it plays. If you run it for a while on the same positions, are the results similar? Same moves? Same depths? Same evaluations? Perhaps similar patterns in the evaluations, indicating similar searches or evaluation terms? Perhaps similar scores on test suites? If all this stuff is different, then it seems like the program has been modified enough for it to be interesting. Definitely interesting enough to be allowed at a tournament... whether or not it should be sold is a different ethical question. -Tom On October 24, 1999 at 05:59:40, Frank Schneider wrote: >On October 23, 1999 at 00:41:29, Robert Hyatt wrote: > >>On October 22, 1999 at 20:28:15, Pete Galati wrote: >> >>>On October 22, 1999 at 18:48:58, James Swafford wrote: >>> >>>>On October 22, 1999 at 07:10:55, Frank Quisinsky wrote: >>>> >>>>>Hello, >>>>> >>>>>you can download a new WinBoard Engine from my webpage. >>>>> >>>>>La Petite (program from Dr. Gabriele Müller, switzerland) is the "Little" sister >>>>>from La Grande.
