rl_cw_2_racetrack CM50270 Reinforcement Learning¶ Graded Assessment: Racetrack¶ In this assignment, you will compare the performance of three reinforcement learning algorithms – On-Policy First-Visit Monte-Carlo Control, Sarsa, and Q-Learning – in a simple racetrack environment. You will then implement a modified TD agent that improves upon the learning performance of a basic Q-Learning agent. Total number
