Parameterized Approximation Algorithms for Weighted Vertex Cover
A vertex cover of a graph is a set of vertices of the graph such that every edge has at least one endpoint in it. In this work, we study Weighted Vertex Cover with solution size as a parameter. Formally, in the ...

An ETH-Tight Algorithm for Bidirected Steiner Connectivity
In the Strongly Connected Steiner Subgraph problem, we are given an n-vertex digraph D, a weight function \(w:A(D)\mapsto {\mathbb {R}}^+\) ...
