**NAME**

damped_newton-- damped Newton nonlinear algorithm

**DESCRIPTION**

Nonlinear damped Newton algorithm for the resolution of the following problem: F(u) = 0 A simple call to the algorithm writes: my_problem P; field uh (Vh); damped_newton (P, uh, tol, max_iter); In addition to the members required for the Newton algorithm (see newton(4)), thespace_normis required for the damped Newton line search algorithm: class my_problem { public: ... Float space_norm (const field& uh) const; };

**IMPLEMENTATION**

template <class Problem, class Field, class Real, class Size> int damped_newton (Problem P, Field& u, Real& tol, Size& max_iter, odiststream* p_derr=0) { return damped_newton(P, newton_identity_preconditioner(), u, tol, max_iter, p_derr); }
