- It depends on how you are failing, and the nature of the nonlinearity. If the
- solution is continuous in slope, you might explore using full newton-raphson
- with line search. The line search provides a dynamically computed over/under
- acceleration factor which can sometimes stablize certain problems, and can
- sometimes speed up the rate of convergence.
