this problem is working again (note: there have been a few changes to Cody machinery so many of the old tricks no longer work :)
I managed to pass your testsuite and yet have a solution of non-zero-size.
Thanks for catching that! I modified the testsuite to fix this but will not rescore this solution (I am trying my testsuite to *only* pass solutions that will get a zero score in Cody as well; it is a bit hard to do that without being too heavy handed and/or interfering with the ways solvers might get that zero score)
"Please refrain from using this sort of Cody tricks to get leading scores in general non-hacking problems. That is just discourteous to other players". Yet you do exactly this on Problem 1. What a tit.
Is this matrix orthogonal?
We love vectorized solutions. Problem 1 : remove the row average.
