SNES_NORM_INITIAL_ONLY

Compute the function and its L2 at iteration 0, but do not update it. Many br

Notes

This method is useful in composed methods, when a true solution might actually be found before SNESSolve() is called. Many brThis option enables the solve to abort on the zeroth iteration if this is the case. Many br

For solvers that require the computation of the L2 norm of the function as part of the method, this merely cancels Many brthe norm computation at the last iteration (if possible). Many br
