I just realized, when I said "predetermined" I didn't explain what that means to me in the context of an infinite number of parallel universes--I take it to mean that the set of possible universe states and the tree dictating which states are reached in the next instant are both fixed permanently. I.e. the universe is a giant NFA ;) wylie
