The agent must choose the optimal pressure amplitude values to manipulate the bubble position in the range of $x/\\lambda_0\\in[0.05, 0.25]$. To train the agent an actor-critic off-policy algorithm (Deep Deterministic Policy Gradient) was used that supports continuous action space, which allows setting the pressure amplitude values continuously within $0$ and $1\\, \\mathrm{bar}$.
