Demystifying Actor‑Critic and PPO: From Policy Gradients to Practical RL

This article provides a thorough, step‑by‑step explanation of reinforcement‑learning theory—covering policy‑based objectives, value‑function definitions, the derivation of policy gradients, actor‑critic architecture, advantage estimation, importance sampling, GAE, and the PPO algorithm—aimed at readers with little prior RL knowledge.
