Integrality gap of the hypergraphic relaxation of Steiner trees: A short proof of a 1.55 upper bound
收藏 引用
OPERATIONS RESEARCH LETTERS 2010年 第6期38卷 567-570页
作者: Chakrabarty, Deeparnab Koenemann, Jochen Pritchard, David Ecole Polytech Fed Lausanne CH-1015 Lausanne Switzerland Univ Penn Philadelphia PA 19104 USA Univ Waterloo Waterloo ON N2L 3G1 Canada
Recently, Byrka, Grandoni, RothvoBand Sanita gave a 1.39 approximation for the Steiner tree problem, using a hypergraph-based linear programming relaxation. They also upper-bounded its integrality gap by 1.55. We desc... 详细信息
