First, I will introduce the background of this paper. Reconfigurable intelligent surface (RIS) is an emerging technology that is widely recognized as a foundational technology for the forthcoming generation of wireless communications. Considering the increasingly intricate radio environment, traditional optimization algorithms have become impractical for their complexities. However, with the continuous advancements in hardware design, computers now possess significantly enhanced computing capability. Consequently, a new alternative algorithm called reinforcement learning (RL) has emerged as a main method for machine learning (ML) based RIS-assisted communication.
