The Actor-Critic Architecture Comparison is a reinforcement learning project that trains an agent to make sequential decisions using Distributed training setup and Evaluation benchmark, implemented with Gymnasium / PettingZoo. The project focuses on a clean formulation of the environment, reward function, and policy, with careful logging and visualization so learning behaviour is easy to inspect. It is a complete RL capstone that demonstrates both algorithm fundamentals and practical training skills.
Many decision-making tasks are sequential: the best action depends on past states and future consequences, making rule-based or one-shot solutions ineffective. Without a reinforcement learning approach built on Evaluation benchmark and Gymnasium / PettingZoo, agents cannot learn from trial and error, adapt to dynamic conditions, or balance short-term gains against long-term goals.
This project models the task as a Markov Decision Process and trains an agent with Gymnasium / PettingZoo using Distributed training setup. The reward function is carefully designed, and Complex environment provides insight into the learned policy. The agent improves over time through exploration and exploitation, and the whole pipeline is reproducible and easy to tune.

The project separates the environment from the agent. The environment implements states, actions, and rewards through Distributed training setup; the agent maintains a policy learned with Gymnasium / PettingZoo and Evaluation benchmark; and the training loop coordinates episodes, logging, and evaluation. A configuration module controls all hyperparameters, and a visualization module renders learning curves and sample rollouts.
