library for nonlinear optimization, wrapping many algorithms for global and local, constrained or unconstrained, optimization
### What happened? When using the GN_AGS solver from the Python API, I realized, that an improvement in the final iteration is not registered properly. When using optimizer.set_maxeval(), and there...
Hi. I have an "R" package which uses NLOPT through the package "nloptR" which basically "wraps" NLOPT. I have been working with the maintainer of the "nloptR" package to identify...
Greetings, Though not exactly an issue but hopefully relevant for folks here too. As a part of our F77 code rewrite effort https://github.com/scipy/scipy/issues/18566, I've rewritten SLSQP in C from scratch...
In mma/ccsaq, when the outer iteration step k is less than "outer_mineval_xftol", the stopping criteria of xtol and ftol are disabled. This is quite useful in some optimization problems where...
For better diagnostics. e.g. with the default algorithm, the output is now: ``` found minimum at f(0.333333,0.296296) = 0.5443310497 after 48 evaluations ```
In the referenced paper, the ISRES algorithm contains the following line for differential variation of the best $k < \mu$: $x_k' \gets x_i + \gamma (x_1 - x_{i+1})$ In the...
### What happened? I used fast-planner with nlopt and found that sometimes nlopt would not be able to optimize the trajectory output speed and heading Angle to 0, and then...
For gradient based optimization algorithms, a stopping criterion based on the gradient would be useful. One could, for example, check that the norm of the gradient is equal to zero...
Hi, Thanks for all your work on nlopt, it is an excellent library. I am interested in using the Sbplx algorithm for gradient-free optimisation of functions with high dimensions (e.g....
Is it possible to somehow modify the stopping criteria in NLopt so that instead of stopping when any of the stopping criteria are satisfied, stop only when all are satisfied?...
