Incremental Network Design with Minimum Spanning Trees
Vol. 21, no. 4, pp. 417432, 2017. Regular paper.
Abstract Given an edgeweighted 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.
