WebThis method is referred to as the Leapfrog method. Note that by reversing the order of the flows, we are actually composing a half-step of the first order splitting with its adjoint (the adjoint of an exact flow is the flow itself), so the Leapfrog method (and Strang splitting in general) is self-adjoint.
