During his stay of 2 weeks, prof. Vallentin will collaborate with the host on at least two research problems: finding better upper bounds for the densities of distance-avoiding sets and finding better approximation algorithms for the maximum-cut problem. Prof. Vallentin will have the opportunity to present a seminar to the local Combinatorics and Optimization group, he will be able to int…
In this project we propose the study of optimization techniques, in particular techniques involving semidefinite programming, for computing upper bounds for the kissing number of the Euclidean space, which is the maximum number of pairwise nonoverlapping unit balls that can simultaneously touch a central unit ball. (AU)
The kissing number problem asks for the maximum number of nonoverlapping unit balls that can simultaneously touch a central unit ball in Rn. Providing good upper bounds for the kissing number in a given dimension is a challenging optimization task; the best bounds currently known have been obtained via semidefinite programming by Bachoc and Vallentin. Fabrício has recently studied this bo…
