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.

Hello Michel,

Thank you for your question. There are many open source and free libraries available for nonlinear optimization and equation solving. Some popular options include:

1. Apache Commons Math - This is an open source Java library that provides a wide range of mathematical functions, including nonlinear optimization and equation solving.

2. SciPy - This is a free and open-source library for scientific computing in Python. It includes modules for optimization and solving equations.

3. GNU Octave - This is a free and open-source numerical computing environment that is compatible with MATLAB. It includes functions for nonlinear optimization and equation solving.

4. NAG Library - This is a commercial library, but it offers a free trial version. It includes a wide range of mathematical functions, including optimization and equation solving, in various programming languages such as Java, C#, and Fortran.

5. ALGLIB - This is a free and open-source numerical analysis library that offers functions for nonlinear optimization and equation solving in various programming languages.

I hope these suggestions are helpful. It is always a good idea to research and compare different libraries to find the one that best fits your needs and programming language preferences. Best of luck with your project!
