Via methods of this object, all of the auglag {nloptr} R Documentation: Augmented Lagrangian Algorithm Description. hpp, that wraps a more natural C++ interface around the NLopt API, which may be more convenient for C++ programmers. This document is an introduction to nloptr: an R interface to NLopt. So there are several things going on here: First, the objective function, F, the equality constraint function, Hc, and the inequality constraint function, Gc, all have to take the same arguments.
