关于图的最小连通变迁集

On Minimum Connecting Transition Sets in Graphs

Thomas Bellitto, Benjamin Bergougnoux

摘要:

禁止变迁图是与一组允许变迁一起定义的图,即可以在图中的行走中连续使用的无序相邻边对。在本文中,我们寻找能够从给定图的任何顶点到任何其他顶点所需的最小转换集。我们证明了该问题是NP难的,并研究了近似算法。我们开发的理论工具,有助于研究这个问题。

英文摘要:

A forbidden transition graph is a graph defined together with a set of permitted transitions i.e. unordered pair of adjacent edges that one may use consecutively in a walk in the graph. In this paper, we look for the smallest set of transitions needed to be able to go from any vertex of the given graph to any other. We prove that this problem is NP-hard and study approximation algorithms. We develop theoretical tools that help to study this problem.
