MOMIX - A Solver for Multiobjective Mixed Integer Convex Optimization
MOMIX is a solver for Multiobjective Mixed Integer Convex Optimization. It is a branch-and-bound method based on the use of properly defined lower bounds, constructed by convex relaxations and by linear outer approximations of the image set in an adaptive way. The algorithm guarantee correctness in terms of detecting both the efficient and the nondominated set of multiobjective mixed integer convex problems according to a prescribed precision. This implementation is realized as MATLAB code. It is published on GitHub and licenced under the GNU Lesser General Public Licence and free to use.
The implementation is based on the paper M. De Santis, G. Eichfelder, J. Niebling, S. Rocktäschel, Solving Multiobjective Mixed Integer Convex Optimization Problems, SIAM Journal on Optimization, 30(4), 3122-3145, 2020. See also OptimizationOnline
Spherical Branch And Bound Algorithms
This Github project includes an R package containing a branch and bound algorithm for computing Fréchet-p-means on the circle and the 2-sphere. Moreover, it provides a wrapper to easily extend these algorithms also to spheres of higher dimension. The repository is supplementary to the paper Eichfelder, G., Hotz, T., Wieditz, J., An algorithm for computing Fréchet means on the sphere, 2019, and was implemented by Johannes Wieditz.
