Currently, we do not have any constrained minimisation or solver
routines -- only unconstrained ones.

At the moment we are only documenting the API and the algorithms, to
reduce the effort. We would plan to add more documentation later as
the library stabilises.

See "Numerical Computation", volumes 1 and 2, by C. Ueberhuber. I
think these books cover most of what you want.
