A note on hop-constrained walk polytopes
暂无分享,去创建一个
A hop-constrained walk is a walk with at most H arcs. The cases H=<3 have been addressed previously. Here, we consider the case H=4. We present an extended formulation for 4-walks and use the projection theorem of Balas and Pulleyblank to derive a complete linear description of the 4-walk polytope.
