WebHence in order to make the criterion independent of the absolute magnitude of x, we use a relative tolerance criterion, given by (1) Note that for both the intervals [1.0000,1.0001] and [1.0000 E +10,1.0001 E +10], we get a relative tolerance of 1.0E-4 .

WebMar 2, 2024 · On the opposite, a stopping criterion based on the norms of the residual may be more erroneous depending on the scaling of the residuals. In my codes, I usually rely on a stopping criterion based on the relative norm of the Newton step, and just for safety I also use a criterion on the residual norm, but the latter is never triggered in practice.
