摘要

非均匀需求网络由一个源和一组与源具有不同最小割值的接收器组成。我们研究这样一种情况，即每个接收器都希望以等于其最小截值的速率从源接收信息。这个问题以前已经公式化了，与均匀情况相比，已经证明非均匀情况不能很好地表征。在此基础上，我们提出了该问题的松弛式，并给出了一些初步的结果

On Achievable Information Rates in Single-Source Non-Uniform Demand Networks

A non-uniform demand network consists of a source and a set of receivers that have different min-cut values from the source. We look at the case where each receiver would like to receive information from the source at a rate that is equal to its min-cut value. This problem has been formulated before, and in contrast to the uniform case, it has been shown that the non-uniform case does not admit a good characterization. Motivated by this, we formulate relaxations of the problem and present some preliminary results
