Ingleton不等式的极小集

The minimal set of Ingleton inequalities

Laurent Guille, Terence Chan, Alex Grant

摘要:

假设使用线性网络码,Ingleton-LP界是多播容量区域的外界。的界限的计算上进行的多面体锥通过采取的基本(香农型)不等式和Ingleton不等式引起的半空间的交集。本文通过得到最小的Ingleton不等式集,简化了该锥的刻画。因此,计算Ingleton-LP界所需的工作量可以大大减少。

英文摘要:

The Ingleton-LP bound is an outer bound for the multicast capacity region, assuming the use of linear network codes. Computation of the bound is performed on a polyhedral cone obtained by taking the intersection of half-spaces induced by the basic (Shannon-type) inequalities and Ingleton inequalities. This paper simplifies the characterization of this cone, by obtaining the unique minimal set of Ingleton inequalities. As a result, the effort required for computation of the Ingleton-LP bound can be greatly reduced.
