A specific algorithmic example of reinforcement learning is Q-learning. In Q-learning, you start with a set environment of states, represented by the symbol ‘S’. In the game Pac-Man, states could be the challenges, obstacles or pathways that exist in the game. There may exist a wall to the left, a ghost to the right, and a power pill above—each representing different states.
