No. What is the purpose of this competition? Unlikely that the reason for it is to pay out an enormous reward, right? Easy or not easy, the fortune is only rewarded to the system that solves the puzzles. The reward is too valuable to be given away easily. Ipso facto, solving the puzzles is deemed challenging by those who present the competition.
Are you writing this under every challenge with a monetary reward? The point of the challenge is that it is hard to do for an AI and easy for a human. Of course it is not easy to solve, that’s the point of the challenge. But the puzzle itself is not very hard.
Human: "They're quite challenging, this might be a trick to engage activity for the purpose of training models."
skrebbel: "You're stupid".
