| These 2 steps are then repeated until the calculation is completed. The number of cycles to be fully calculated $N_i$ and the number of "jumped" cycles $N_j$ can vary during the simulation. One can also pick the results to be extrapolated during the jump. \\ | These 2 steps are then repeated until the calculation is completed.
