DMNF

 
Finds a local minimum of a continuously differentiable function.
Finite-difference gradients and secant Hessian approximations are used. Uses a
variant of Newton's method with a quasi-Newton (BFGS) Hessian updating method,
and a model/trust-region technique to aid convergence from poor starting
values. (This is subroutine SMSNO of ACM Trans. Math. Softw. 9 (1983) 503-524.).
 
Classes  :  G1b1a . Unconstrained optimization of a smooth multivariate
                  function, user provides no derivatives
 
Type     : Fortran subroutine in PORT library (NL3OPT sublibrary).
Access   : Proprietary. Many implementations available.
