TVGP Change Log

Initial Release (May 20, 2008)

Second Release (October 14, 2008): Changed algorithms to give consistent convergence criteria; changed test code to facilitate esier comparison between the algorithms, and to save the solutions obtained for each convergence tolerance as eps figures. Also save the figure that shows comparitive performance of three methods as an eps file. Run data is saved in a mat file to allow regenereration of tabular data and figures as needed. This release contains an implementation of PDHG, a very fast primal-dual gradient projection method not mentioned in the paper but rather discussed in a later paper of Minqiang Zhu and Tony Chan (May, 2008).
