Descripción del Proyecto

The minfx project is a Python package for numerical optimization. It provides a large collection of standard minimization algorithms, including the line search methods (steepest descent, back-and-forth coordinate descent, quasi-Newton BFGS, Newton, and Newton-CG), the trust-region methods (Cauchy point, dogleg, CG-Steihaug, and exact trust region), the conjugate gradient methods (Fletcher-Reeves, Polak-Ribiere, Polak-Ribiere +, and Hestenes-Stiefel), the miscellaneous methods (Grid search, Simplex, and Levenberg-Marquardt), and the augmented function constraint algorithms (logarithmic barrier and method of multipliers).

1.0.1

Este lanzamiento supone el cambio inevitable de python numéricas para NumPy, algunas mejoras en los gradientes de cómo desaparecidos y los modelos con los parámetros no sean manipulados, y un interruptor de GPLv2 a GPLv3.
Tags: Minor feature enhancements
This release involves the inevitable switch from
Numeric python to numpy, a few improvements in how
missing gradients and models with no parameters
are handled, and a switch from GPLv2 to GPLv3.

1.0.0

Este código se originó como parte de la relajación del proyecto dentro de la «reducir o 'directorio. Minfx es completa, muy estable y bien probado, y se ha independizado como su propio proyecto para el beneficio de otros proyectos científicos, analíticos o numéricos.
Tags: Initial freshmeat announcement
This code originated as part of the relax project within the 'minimise/' directory. Minfx is complete, very stable, well tested, and has been spun off as its own project for the benefit of other scientific, analytical, or numerical projects.
