In the Cart-Pole game, you will find a pole attached by an un-attached joint to the cart, which moves on a frictionless track. At the beginning of each game, the pole starts at the upright position and the goal is to hold it in the upright position as long as possible or for a given number of time steps. One can control the Cart-Pole system by applying a force of +1 and -1 (move the cart either to the right or to the left) and prevent the pole from falling over. The game/episode ends when cart moves more than 2.4 units from the center or when the pole is more than 45 degrees from the vertical.
