具有最小生成树的增量网络设计

Incremental Network Design with Minimum Spanning Trees

Konrad Engel, Thomas Kalinowski, Martin W. P. Savelsbergh

摘要:

给定一个边加权图$G=(V,E)$和一个集合$E_0\subset E$,具有最小生成树的增量网络设计问题要求最小化$\sum_{t=1}^Tw(X_t)$的边序列$e'_1,\ldots,e'_T\in E\setminus E_0$,其中$w(X_t)$是子图$(V,E_0\cup\{e'_1,\ldots,e'_t\})$和$T=\lvert E\setminus E_0\rvert$的最小生成树$X_t$的权重。我们证明了这个问题可以解决的贪婪算法。

英文摘要:

Given an edge-weighted graph $G=(V,E)$ and a set $E_0\subset E$, the incremental network design problem with minimum spanning trees asks for a sequence of edges $e'_1,\ldots,e'_T\in E\setminus E_0$ minimizing $\sum_{t=1}^Tw(X_t)$ where $w(X_t)$ is the weight of a minimum spanning tree $X_t$ for the subgraph $(V,E_0\cup\{e'_1,\ldots,e'_t\})$ and $T=\lvert E\setminus E_0\rvert$. We prove that this problem can be solved by a greedy algorithm.
