A PTAS for Weighted Triangle-free 2-Matching
Miguel Bosch-Calvo, Fabrizio Grandoni, Yusuke Kobayashi +1
In the Weighted Triangle-Free 2-Matching problem (WTF2M), we are given an undirected edge-weighted graph. Our goal is to compute a maximum-weight subgraph that is a 2-matching (i.e…

A Approximation for -Vertex-Connectivity
Miguel Bosch-Calvo, Fabrizio Grandoni, Afrouz Jabal Ameli
The 2-Vertex-Connected Spanning Subgraph problem (2VCSS) is among the most basic NP-hard (Survivable) Network Design problems: we are given an (unweighted) undirected graph . Ou…

A -Approximation for Two-Edge Connectivity
Miguel Bosch-Calvo, Mohit Garg, Fabrizio Grandoni +3
The 2-Edge-Connected Spanning Subgraph problem (2ECSS) is among the most basic survivable network design problems: given an undirected and unweighted graph, the task is to find a s…
