Projeto Descrição

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

Esta versão inclui a opção inevitável em python numérico para numpy, algumas melhorias em gradientes como desaparecidas e modelos sem parâmetros são manipulados, e uma mudança de GPLv2 para 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 surgiu como parte do projeto relaxar dentro do 'minimizar /' diretório. Minfx está completo, muito estável e bem testado, e foi desmembrada em seu próprio projeto para o benefício de outros projetos científicos, analítica ou numérica.
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.
