Im currently enrolled in an AI course and we are starting with state space search problems. My professor always seems to ask, given a certain problem, what is the estimate size of the state space? It's been 3 years since ive taken a course in discrete math which is the type of question I am asking.

How can I use things like branch factor and depth to estimate state space?
