    Learn the foundations of reinforcement learning and Markov decision processes, then compare PPO and SAC through their mechanics, use cases, strengths, weaknesses, and practical tradeoffs.

    A practical guide to two leading reinforcement-learning algorithms: how Markov decision processes frame the problem, why PPO favors stable updates, and why SAC emphasizes sample efficiency and exploration.
