library for nonlinear optimization, wrapping many algorithms for global and local, constrained or unconstrained, optimization
I encountered this problem when I used nlopt's matlab interface in win10 to solve a high-dimensional optimization problem containing nonlinear inequality constrains (the optimization variable is a column vector). After...
Hello. I would like to know if NLOpt has any support for AMPL integration, or any other tool allowing automatic differentiation. For instance, [NLOpt.jl](https://github.com/JuliaOpt/NLopt.jl), provides a derivative-free interface. Although I...
Hello, I am using nlopt in conjunction with meep adjoint. I would like to set checkpoints in the optimizations I make. Does nlopt natively allow for something like this? Thanks
STOGO fails to optimize a simple quadratic problem with bound constraints: ``` #include #include #include #include #include #include double myvfunc(const std::vector &x, std::vector &grad, void *data) { (void)data; if (!grad.empty())...
PRAXIS in this example leads to x=[nan,nan] eventhough this is a bounded problem ``` #include #include #include #include #include #include double myvfunc(const std::vector &x, std::vector &grad, void *data) { (void)data;...
Dear NLopt maintainers, This is Dr. Zaikun Zhang from the Hong Kong Polytechnic University. Together with Professor [N.I.M. Gould](https://www.numerical.rl.ac.uk/people/nimg/), I am responsible for maintaining the derivative-free optimization solvers of late...
Hi， I'm playing around with the MATLAB version of Nlopt and find it doesn't support user to modify Algorithm-specific parameters. There's also no such guide in the Documentation, however Python...
Honor -DNLOPT_RPATH=(ON|OFF) to link RPATH into installed NLopt libraries (Default: ON).
Hello, I am using the algorithm Sbplx (LN_SBPLX). I have disabled the stop criteria based on the x tolerance (relative and absolute) using the (C++) methods set_xtol_rel(value) and set_xtol_abs(value) with...
I'm trying to port your library, enabling compiler warnings produces many that could be fixed and actually I think fixed them would enhance the quality of the lib too much....
