Nonlinear optimisation, equations solving, numerical libraries

[lalbatros]

Hello,

I would be interrested to learn if there are some (new) open source and/or possibly free librairies available for nonlinear optimisation and equations solving.

I would be mostly interrested in modern languages like java or C# . "Clean" fortran could also be interresting as long as it is not goto-spagetti code.

Thanks for your suggestions,

Michel

You can also ask around on #java or #C# on efnet.
