solution or not and if they do then the algorithm goes to the solution even though there still may be exponentially many spruce local minima at lower energy so they're not really spruce because the gradient flow just never ever sees them with probability that is that is one up to some exponentially small factor so here i should be about a middle of the talk and i want to conclude about the spike matrix model so i showed you you know this is i think the first time that we have a close form conjecture for the threshold of what
