Detailed Description

Requires reduction in residual norm compared to initial norm.

At iteration zero, this computes $||F_0||$ and is unconverged.

Returns a converged status if $||F_k|| < ||F_0|| * \mbox{tolerance}$ , where $k$ is the nonlinear iteration number.

Test the stopping criterion

The test can (and should, if possible) be skipped if checkType is NOX::StatusType::None. If the test is skipped, then the status should be set to NOX::StatusTest::Unevaluated.

Implements NOX::StatusTest::Generic.
