This is awesome. I did exactly this for a course project in 2012. While the travelling salesman problem code seems to have been refactored out, I have a C++ library for SOMs and hierarchical SOMs that are attatched to some openGL code that demonstrates the categorization of RGB colors by label. If you can excuse the embarassing mess of file structure, the core lib is here, buried among a dozen other pet projects from my student days: https://github.com/KyleGalvin/Typhoon/blob/master/Cpp/SOM.cpp https://github.com/KyleGalvin/Typhoon/blob/master/Cpp/SOM.cp... Edit: it seems (on second glance) the above link is exactly the TSP problem, wired up with SDL. The core library is here: https://github.com/KyleGalvin/Typhoon/blob/master/Cpp/src/somIII.hpp https://github.com/KyleGalvin/Typhoon/blob/master/Cpp/src/so...
