might have attended ms or a workshop on neural net okay this is also we don't want shallow Nets here so this is a very very shallow neural networks so suppose you've got an algorithm and this algorithm is solving a problem that solvable in so-called non-deterministic exponential time so this is like some just gigantic unfathomable class so this is problems where the solution takes exponentially many bits to describe and then verifying the solution is exponentially so this is just some gigantic class of problems ok the
