Before revision:  A uniform sampling method is implemented for the discretization of the Onsager functional, and the solution landscape of the Onsager functional is constructed by using the saddle dynamics coupled with downward/upward search algorithms.
After revision:  A uniform sampling method is implemented for the discretization of the Onsager functional, and the solution landscape of the Onsager model are constructed using saddle dynamics coupled with downward/upward search algorithms.
