@lmoneta Hi, happy to see this moving forward! FYI libcmaes recently went under the same umbrella as the other CMA-ES reference implementations, https://github.com/CMA-ES/libcmaes. Don't hesitate to file issues if we can help with integration from the libcmaes side.

this is awesome @lmoneta and @beniz
I am so happy to see this code and glad to be a reviewer.

Let's see my comments in the files :D

I leave some comments about some small details in the code.

I am still running some tests and tutorials, which is taking some time.

@beniz, sorry for starting this after a long time, but I think it is good to have this library integrated in ROOT.
I see now cameos can early build with cmake and this will make it easier to also download and install the library automatically.
I will try to fix issues from the ROOT side myself, but feel free to comment and correct me
