Answer 1

The dlib C++ library has a number of optimizers in it including L-BFGS. It's free and the optimization tools are header-only so there is nothing to install or configure. There is also a relevant example program that shows you how to use the L-BFGS optimizer.

If still someone looking for, use LBFGS++ they also introduce the recently Box-constrained version. I have been using this for a while. You can find some good examples on their official website.
