We consider the problem of maximizing a non-negative monotone submodular function subject to a knapsack constraint, which is also known as the Budgeted Submodular Maximization (BSM) problem. Sviridenko (2004) showed that by guessing 3 appropriate ele

We obtain approximation ratio 4 + 2 l ≈ 4 + 4 lg k lg n − lg k for the (undirected) k -Connected Subgraph problem, where l = ⌊ lg n − lg k + 1 2 lg k + 1 ⌋ is the largest integer such that 2 l − 1 k 2 l + 1 ≤ n .

In the Tree Augmentation problem we are given a tree T=(V,F) and a set E of edges with positive integer costs {c_e:e in E}. The goal is to augment T by a minimum cost edge set J subseteq E such that T cup J is 2-edge-connected. We obtain the followin

We consider the directed Rooted Subset k -Edge-Connectivity problem: given a digraph \(G=(V,E)\) with edge costs, a set \(T \subset V\) of terminals, a root node r, and an integer k, find a min-cost subgraph of G that contains k edge disjoint rt-path

We consider network design problems in which we are given a graph \(G=(V,E)\) with edge costs, and seek a min-cost/size 2-node-connected subgraph \(G'=(V',E')\) that satisfies a prescribed property.

In this paper we study covering problems that arise in wireless networks with Unmanned Aerial Vehicles (UAVs) swarms. In the general setting we want to place a set of UAVs that should cover a given set of planar users under some constraints and we wa

Motivated by some open problems posed in [13], we study three problems that seek a low degree subtree T of a graph \(G=(V,E)\). In the Min-Degree Group Steiner Tree problem we are given a collection of node subsets (groups), and T should contain a no
