http://icmsec.cc.ac.cn/Uploads/old/news/2015/20150808.pdf Web19 de jul. de 2015 · The ADMM ( 1.2) for solving two-block convex minimization problems (i.e., N=2) has been studied extensively in the literature. The global convergence of ADMM ( 1.2) when N=2 has been shown in [ 11, 12 ]. There are also some very recent works that study the convergence rate properties of ADMM when N=2 (see, e.g., [ 13 – 18 ]).
