SUMMARY:Tutte Colloquium - Walaa Moursi
CLASS:PUBLIC
DESCRIPTION:TITLE: The Chambolle-Pock algorithm revisited: splitting opera
 tor and\nits range with applications\n\nSpeaker:\n Walaa Moursi\n\nAffilia
 tion:\n University of Waterloo\n\nLocation:\n MC 5501\n\nABSTRACT: Primal
 -dual hybrid gradient (PDHG) is a first-order method\nfor saddle-point pro
 blems and convex programming introduced by\nChambolle and Pock. Recently\,
  Applegate et al. analyzed the behavior\nof PDHG when applied to an infeas
 ible or unbounded instance of linear\nprogramming\, and in particular\, sh
 owed that PDHG is able to diagnose\nthese conditions.
