摘要
The paper discusses a new view on globalization techniques for Newton's method. In particular, strategies based on "natural level functions" are considered and their properties are investigated. A "restrictive monotonicity test" is introduced and theoretically motivated. Numerical results for a highly nonlinear optimal control problem from aerospace engineering and a parameter estimation for a chemical process are presented.
