The 16 in test case 4 should be a 6.
It's changed now. Good catch.
FYI: at this moment all solutions below score 150 are hard-coded ones
I've added some randomness to the test suite questions to stop the look-up tables from working properly. Thanks for the heads up on that. As you may have noticed, it's been a while since I submitted this problem!
Solutions aren't unique: f([1;2;3]) = {[1,2,3],[1,3,2],[2,1,3]}
Nice problem!
It's quite challenging!
combvec is no longer usable in Cody? No more Neural Network toolbox, I guess.
