Reinforcement Learning Algorithms

For a Reinforcement Learning class, I worked on a few algorithms :

• Policy Iteration
• Value Iteration
• SARSA
• Q-Learning

to work on the OpenAI gym Cliff Walking problem (for SARSA and Q-Learning) and Sutton's Reinforcement Learning book Grid World exercice (for Policy Iteration and Value Iteration).

How to use ?

python main.py {RD, VI, PI, SARSA, QL} With {RD: Random, VI: Value Iteration, PI: Policy Iteration, SARSA: SARSA, QL: Q-Learning} Use python main.py -h to know more.

For Policy Iteration and Value Iteration, plots will appear, showing a map for each move (LEFT, RIGHT, UP, DOWN) colored when the given move is the best for the square. For SARSA and Q-Learning, plots will appear, showing the final reward after each episode. The parameters have been tuned so that the learning works (reward increase along the episodes).
