Why do you say AlphaGo is brute-force? Brute force is defined as: "In computer science, brute-force search or exhaustive search, also known as generate and test, is a very general problem-solving technique that consists of *systematically enumerating all possible candidates* for the solution and checking whether each candidate satisfies the problem's statement."
The whole point of the policy network is to avoid brute-force search, by reducing the branching factor...
