加权无标度网络的最小权生成树

Minimum weight spanning trees of weighted scale free networks

O. Melchert

摘要:

在本讲座中,我们将考虑最小权重生成树(MST)问题,即,最简单且最重要的组合优化问题之一。我们将讨论一个特殊的贪心算法,允许计算无向加权图的MST,即Kruskal算法,我们将研究加权无标度随机图的MST的结构。这意味着澄清MST的结构是否对底层无标度图的边权重和拓扑之间的相关性敏感。

英文摘要:

In this lecture we will consider the minimum weight spanning tree (MST) problem, i.e., one of the simplest and most vital combinatorial optimization problems. We will discuss a particular greedy algorithm that allows to compute a MST for undirected weighted graphs, namely Kruskal's algorithm, and we will study the structure of MSTs obtained for weighted scale free random graphs. This is meant to clarify whether the structure of MSTs is sensitive to correlations between edge weights and topology of the underlying scale free graphs.
