Dear developers, In Petsc user manual, it was mentioned that Trust-Region Method is working upon MINPACK routines. I need to know more details of the procedure like:
1- How to update the TR bound? 2- How solving the minimization subproblem? 3- How to calculate the search direction? Is the "dogleg" direction is used? Thanks a lot, BehZad -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.mcs.anl.gov/pipermail/petsc-users/attachments/20111212/9cf4dfe3/attachment.htm>
