DESCRIPTION:Summary \n\nTITLE: The Chambolle-Pock algorithm revisited: spl
 itting operator and\nits range with applications\n\nSpeaker:\n Walaa Mours

 ACT: Primal-dual hybrid gradient (PDHG) is a first-order method\nfor sadd
 le-point problems and convex programming introduced by\nChambolle and Pock
 . Recently\, Applegate et al. analyzed the behavior\nof PDHG when applied 
 to an infeasible or unbounded instance of linear\nprogramming\, and in par
 ticular\, showed that PDHG is able to diagnose\nthese conditions.\n
