Abstract
We consider the following NP-hard problem. Given an undirected complete edge-weighted graph and positive integers m, D, the goal is to find m edge-disjoint spanning trees with diameter D of maximum total weight in complete undirected graph. We propose an \(\mathcal O(n^2)\)-time approximation algorithm for the problem, where n is the number of vertices in the input graph. For the case when edge weights are randomly uniformly chosen from the interval (0; 1), we prove sufficient conditions under which the proposed algorithm gives asymptotically optimal solutions.
The study was carried out within the framework of the state contract of the Sobolev Institute of Mathematics (project FWNF-2022-0019).
