Anselme Russel Affane Moundounga I would recommend you look at the source code of numerical algorithms in the GNU scientific library, those contain state-of- the-art implementations in C/C++ for algorithms found in NR3, but optimized + adapted for edge/real world cases. It's a great exercise to compare your own code against it as well.

Hope this helps,

Hi dear Ben,

Nice tips, thanks! I'll visit and try to implement and compare the GSL routing with the NR3 ones.

Hi Ben Cardoen ,

In the GSL routines, I've not find routines about the hidden Markov Models, Expectation-maximization, Gaussian Mixtures Models, K-means clustering and many others used in machine learning and classification methods.

Are there others like GSL that you known?
