DRMNF

 
Reverse communication version of PORT's MNF. 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.
 
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.
Precision: Double.
 
Usage    : CALL DRMNF (D, FX, IV, LIV, LV, N, V, X)
 
Details  : Fullsource Source
Sites    : (1) NETLIB
