I have a physical problem to solve in which a waving filament in fluid medium propels itself (think of a beating sperm tail). Why use NLopt, when some of the same algorithms are available elsewhere? Several of the algorithms provided by NLopt are based on free/open-source packages by other authors, which we have put together under a common interface in NLopt. However, we also provide a C++ header file, nlopt. The bold text must mean that if I use the NLOPT default option, I shouldn't need to bother with setting any path. jl, Evolutionary. Also, it has some solvers written by other authors and connected to the package, some of them were translated from Fortran by f2c.

NLopt is a library, not a stand-alone program—it is designed to be called from your own program in C, C++, Fortran, Matlab, GNU Octave, or other languages. So, you can just change them into equality constraints instead of inequality constraints and it should get the same answer. csc_matrix ([[ 4 , 1 ], [ 1 , 2 ]]) q = np . As a first example, we'll look at the following simple nonlinearly constrained minimization problem: minx∈R2x2 subject to x2≥0, x2≥(a1x1+b1)3, and x2≥(a2x1+b2)3 for parameters a1=2, b1=0, a2=-1 The NLopt includes interfaces callable from the Matlab and GNU Octave (a free-software Matlab-like program), using identical syntax.
