[petsc-users] question about SNESLINESEARCHBT

[Michael Povolotskyi]

Dear Petsc developers and users,
I solve nonlinear systems with Newton Broyden method with Petsc.
I use line search algorithm of type SNESLINESEARCHBT.
Usually it works, but sometimes diverges. I want to change its 
parameters that are listed in
http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/SNES/SNESLINESEARCHBT.html#SNESLINESEARCHBT

Is there any way to set them in the code rather then from the command line?
Thank you,
Michael.
