I am solving a non-linear problem and using a finite difference approximation with coloring to compute the Jacobian matrix.

There are several coloring algorithms available in PETSc as indicated here:

And I was wondering how to switch from one to another in the Jacobian setup routine and also how to check which coloring algorithm I am currently using.

Thank you.
