 Description

BUGS/ISSUES:
- nested solvers and related stuffs
- fix NelderMead post-processing when input contains systems
- fix dynamic Assistance strings of Ridder's functions
- CSV summary name from user input (CSV summary name check)
- NCGM/NelderMead issues with scalar functions
- optimization issues with scalar functions (min like min of squared function)
- fix JacobianCD (forum)
- null perturbation/null epsilon issues
- others reported in the BTS
 
Algorithms (in progress):
- BFGS (Dropbox)
- multiple roots: signum iteration (Dropbox)
- linear solver (forum)
- Wrappers (Maximize, Minimize)
 
Algorithms (to investigate):
- Powell's method
- Particle Swarm Optimization
- JCFN, JFSJ, L-BFGS

Under development:

- code changes to make algorithms faster

Under investigation:

- single last argument with list input (like in maxima plugin) to enable advanced features (iterations, summary, etc...); this wil be more extensible and will produce less functions with smart descriptions.

- change of project name ("Solvers Library" or something similar, to add also linear solvers)
