关于图的旅行商多面体、对称旅行商多面体和度量锥之间关系的注记

A note on the relationship between the Graphical Traveling Salesman Polyhedron, the Symmetric Traveling Salesman Polytope, and the Metric Cone

Dirk Oliver Theis

摘要:

在这个简短的交流中,我们观察到,图形旅行商多面体是正正交与对称旅行商多面体的Minkowski和和度量锥的极的交集。这几乎是从已知的事实中得出的。有两个原因使我们发现这个观察值得交流:它非常令人惊讶;它有助于理解这两个重要多面体家族之间的关系。

英文摘要:

In this short communication, we observe that the Graphical Traveling Salesman Polyhedron is the intersection of the positive orthant with the Minkowski sum of the Symmetric Traveling Salesman Polytope and the polar of the metric cone. This follows almost trivially from known facts. There are two reasons why we find this observation worth communicating none-the-less: It is very surprising; it helps to understand the relationship between these two important families of polyhedra.
