The study relies on solving the incompressible Navier Stokes equations using Adaptive Mesh Refinement
techniques, efficiently deployed on massively parallel computer architectures. The coordinated swimming
is achieved through synchronised control of the individual swimmer motions in response to the flow environment
by the Remember and Forget Experience Replay Reinforcement Learning framework developed in our group.
We examine the variation of hydrodynamic benefits with a progressive increase of the school size.
We demonstrate the importance of controlling the vorticity field generated by the synchronised swimmers and
present hydrodynamic quantities (pressure, drag) for the individual swimmers and the school.
