Reinforcement Learning Section with new Questions

[arpitsinghgautam]

Hi @moe18

I noticed that the reinforcement learning section currently includes a grpo question, but there isn't much more. I'd like to propose adding a set of targeted questions that cover a range of RL topics and difficulty levels. Here’s a summary of the questions I’m suggesting:

Category: Beginner
Gridworld Policy Evaluation
Epsilon-Greedy Action Selection

Category: Intermediate
Q-Learning Update
Deep Q-Network (DQN) Update Step

Category: Advanced
Proximal Policy Optimization (PPO) Loss Function

These questions are designed to enhance the pool by addressing various core aspects of reinforcement learning—from basic policy evaluation and action selection to more advanced deep RL and policy gradient methods. They cater to a wide range of difficulty levels.

Let me know if this sounds good, then I will start adding these questions.

that sounds great! that would be very helpful to the site

I have added the first question @moe18 please check and let me know, also the question number I used the issue number itself, ket me know If I need to change that. I will keep adding the remaining RL questions here 1 by 1.
