My summary of this idea has been that life is a non-convex optimization problem. Hill-climbing will only get you to the top of the hill that you're on; getting to other hills requires periodic re-initializing. Existing non-convex optimization techniques are often heuristic rather than provably optimal, and when they are provable, they're slow.
