EDIT: I'm gonna modify my question a bit: The solution doesn't have to be the ONLY optimal one, it just has to be optimal.

In other words, say I had an 8 move solution for a scramble (n=8). Can I be certain that this solution is optimal?

Can n be found using only a simple tree search starting from a solved cube?
