Made a quick change. This should cause a lot of old solutions to fail. Will process the queue as fast as possible! Thanks!

Yaroslav, I agree entirely. Unfortunately, every time on other problems that I changed the test suite, the look up tables just came back anyways. We need to eventually randomize test suites. When that is supported well, I will do it! Doug

Suresh, Which test case? Please be more explicit. These were all taken from a list of known problems, so I need more info to understand if one is flawed.

For which test statement is there not a unique solution? We need to fix the test suite if there are two answers of same score.

Doug Hull submitted a Comment to Problem 753. Solitaire Cipher

Richard, I see the difference in our code: if j2==27 d=[28 d(2:26) d(28) d(1)]; end proper implementation would be: if j2 == 27 d = [d(1) 28 d(2:26) d(28)]; end Basically, it has to skip two cards down the deck. I will clean up the wording, as I have seen several do this on internal implementations here too. Thanks, Doug
