wip/nlopt 2.10.0 NetBSD

NLopt is a free/open-source library for nonlinear optimization, providing a common interface for a number of different free optimization routines available online as well as original implementations of various other algorithms.

Its features include:

• Callable from C, C++, Fortran, Matlab or GNU Octave, Python, GNU Guile, Julia, GNU R, Lua, and OCaml.
• A common interface for many different algorithms -- try a different algorithm just by changing one parameter.
• Support for large-scale optimization (some algorithms scalable to millions of parameters and thousands of constraints).
• Both global and local optimization algorithms.
• Algorithms using function values only (derivative-free) and also algorithms exploiting user-supplied gradients.
• Algorithms for unconstrained optimization, bound-constrained optimization, and general nonlinear inequality/equality constraints.
