Alfonso Nieto-Castanon submitted a Comment to Problem 2873. feeling VERY lucky?

Hi Jean-Marie, thanks, it is a pleasure to be back! In my opinion that does not work simply because the Matlab session where your solution is being evaluated is not a "clean" (just started) matlab session. Rather the testsuite will be evaluated by one of several Matlab servers available at any given timepoint, and while the variable space is cleared, and the directory structure is deleted before each evaluation there are many other properties (like the state of random streams, functions in memory, etc.) which are not reinitialized and will be influenced by the particular server's history of evaluated solutions (e.g. this is what allows hacks like freepass to work)

Hi Anupam, could you please correct this testsuite? (just change the line that reads "y_correct = 16 3 2 13;5 10 11 8;9 6 7 12;4 15 14 1" to read instead "y_correct = [16 3 2 13;5 10 11 8;9 6 7 12;4 15 14 1]")

(not to mention that this particular testsuite does not even test for anything at all)

While I understand that experimenting with creating problems is half the fun of Cody this is a somewhat extreme example of a repetitive problem that seems unnecessary, so yes, I agree with Jean-Marie here that perhaps some form of user-based curation like that in Answers or minimum user-requirements for creating problems might help

but I liked your fix for the ans trick, I wish that was part of the standard cody scoring!

unless I am misunderstanding, y_correct should be 2 for test #2 (e.g. path 1-2-1)
