A Survey of Deep Reinforcement Learning Based on Multi-Particle Environments

Abstract

This paper extensively explores the application of deep reinforcement learning within multi-agent environments, a domain marked by intricate challenges and burgeoning opportunities. Multi-agent environments inherently entail the presence of multiple interacting intelligent agents, thereby amplifying the complexity of decision-making and control. Traditional reinforcement learning methods, when confronted with these intricate settings, manifest limitations that have prompted a compelling shift towards the fusion of deep learning and reinforcement learning. The journey commences by elucidating the multifaceted challenges and intricacies pervasive in multi-agent environments. It systematically delineates the constraints of conventional reinforcement learning techniques, underscoring their inadequacies in effectively addressing the multifarious complexities presented by these environments. As the narrative unfolds, it places a spotlight on the transformative potential of deep learning in surmounting the formidable challenges associated with decision-making in multi-agent settings. A critical examination ensues, encompassing a thorough review of pioneering applications of methodologies such as value functions, policy gradients, and actor-critic approaches within the realm of multi-agent systems. Through an exhaustive exploration of existing literature, this article endeavors to unveil the vanguard developments and persisting challenges within the domain of deep reinforcement learning in multi-agent environments. Furthermore, this paper conducts a comparative analysis of the performance of two prominent algorithms, namely Q-learning and the Deep Q Network (DQN) algorithm. This analysis serves as a compass, elucidating the trajectory of development within the sphere of deep reinforcement learning. Ultimately, this paper acts as a compass, guiding future research and innovation in the dynamic and promising field of deep reinforcement learning within multi-agent environments.
