Abstract

In this paper, we propose several integer programming (IP) formulations to exactly solve the minimum-cost λ-edge-connected k-subgraph problem, or the (k, λ) -subgraph problem, based on its graph properties. Special cases of this problem include the well-known k-minimum spanning tree problem (if λ= 1), λ-edge-connected spanning subgraph problem (if k=
