📝 摘要(中文)
近年来,深度强化学习在流控问题中的应用日益增多,催生了一个新兴研究领域,专注于现有算法在数值流体动力学环境中的耦合与适应。尽管这一领域仍处于起步阶段,但在短时间内取得了多项成功,部分归功于推动社区扩展的开源努力。然而,该领域仍缺乏一个共同基础,以确保结果的可重复性,并提供适当的基准测试基础。为此,本文提出了Beacon,一个开源基准库,包含七个具有不同特征、动作和观察空间特征以及CPU需求的轻量级1D和2D流控问题,并提供了参考控制解决方案。

📄 摘要(原文)
Recently, the increasing use of deep reinforcement learning for flow control problems has led to a new area of research, focused on the coupling and the adaptation of the existing algorithms to the control of numerical fluid dynamics environments. Although still in its infancy, the field has seen multiple successes in a short time span, and its fast development pace can certainly be partly imparted to the open-source effort that drives the expansion of the community. Yet, this emerging domain still misses a common ground to (i) ensure the reproducibility of the results, and (ii) offer a proper ad-hoc benchmarking basis. To this end, we propose Beacon, an open-source benchmark library composed of seven lightweight 1D and 2D flow control problems with various characteristics, action and observation space characteristics, and CPU requirements. In this contribution, the seven considered problems are described, and reference control solutions are provided.
