536 constraint surface, $\Delta\mathbf x$ and $\Delta\lambda$ are the
538 user-provided consistency parameter determining the shape of the constraint surface.
539 Generally, $\psi^2 > 0$ leads to a hyper-sphere constraint surface, while
540 $\psi^2 = 0$ leads to a hyper-cylinder constraint surface.
542 Since the solution will always fall on the constraint surface, the method will often
