q learning?

Answer 1

Q-learning is a reinforcement learning technique that works by learning an action-value function that gives the expected utility of taking a given action in a given state and following a fixed policy thereafter.

A strength with Q-learning is that it is able to compare the expected utility of the available actions without requiring a model of the environment.
