Figure 1: Visualization of the searched solver parameters of DDPM/VP and Rectified Flow. We limit the order of solver coefficients of the last two steps for 5/6 NFE. The left images show the absolute value of searched coefficients c j i . The right image shows the searched timesteps of different NFE and the fitted curves.
