- Abstract: Reinforcement Learning (RL) has emerged as a highly effective technique for
addressing various scientific and applied problems. Despite its success,
certain complex tasks remain challenging to be addressed solely with a single
model and algorithm. In response, ensemble reinforcement learning (ERL), a
promising approach that combines the benefits of both RL and ensemble learning
(EL), has gained widespread popularity. ERL leverages multiple models or
training algorithms to comprehensively explore the problem space and possesses
strong generalization capabilities. In this study, we present a comprehensive
survey on ERL to provide readers with an overview of recent advances and
challenges in the field. Firstly, we provide an introduction to the background
and motivation for ERL. Secondly, we conduct a detailed analysis of strategies
such as model selection and combination that have been successfully implemented
in ERL. Subsequently, we explore the application of ERL, summarize the
datasets, and analyze the algorithms employed. Finally, we outline several open
questions and discuss future research directions of ERL. By offering guidance
for future scientific research and engineering applications, this survey
significantly contributes to the advancement of ERL.
