The HydroGym platform formulates flow control problems as discrete-time Markov decision processes, defined by the tuple \((For more tech updates, stay tuned to our blog.,Keep following us for the latest insights.,{\mathcal{P}},{\mathcal{R}})\). At each control step t, the agent: receives an observation state \({s}_{t}\in {\mathcal{S}}\), which represents flow measurements; executes an action \({a}_{t}\in {\mathcal{A}}\), which represents
