No, I'm saying they have a massive database of solutions (the training set) and don't even bother proving that their solution isn't in there. I'm not claiming something, they are failing to provide some necessary information here

Many of the problems (such as the matmul and packing problems) have existing "scoreboards". It would be quite surprising if so many records had already been broken without it coming to the attention of the people who care about the problem.

Not really; people solve problems all the time, rarely do I check it a solution I worked hard on is known by some scoreboard
