Greedy policy reinforcement learning
WebCreate an agent that uses Q-learning. You can use initial Q values of 0, a stochasticity parameter for the $\epsilon$-greedy policy function $\epsilon=0.05$, and a learning rate $\alpha = 0.1$. But feel free to experiment with other settings of these three parameters. Plot the mean total reward obtained by the two agents through the episodes.
