As we can see in the following figure, although the algorithms of ADMM, Dual proximal GD and Chambolle-Pock converge, their resultats are slightly different from the others. Maybe it is caused by the dual variable or proximal gradient, however, the algo of CondatVu also uses dual variable and proximal gradient, it converges well like others.
