Re: [petsc-users] Unconstrained optimization question

You can use the PETSC_OPTIONS environment variable to specify options if you don't pass the command line arguments through. You can set -tao_grtol smaller to handle this difference in scales between the objective and the gradient, though applying ZjQcmQRYFpfptBannerStart

Re: [petsc-users] Unconstrained optimization question

This is a fortran code that doesn’t make use of argc,argv (I tried running with the runtime options anyway, in case you implemented some magic I’m not familiar with, but didn’t see anything new in the output). I have a call to TaoView(tao, PETSC_VIEWER_STDOUT_SELF,ierr) in the code and it report

[petsc-users] Unconstrained optimization question

Hi, I’m trying to do an unconstrained optimization on a molecular scale problem. Previously, I was looking at an artificial molecular problem where all parameters were of order 1 and so the objective function and variables were also in the range of 1 or at least within a few orders of magnitude
