摘要:

基于最短路径的图论问题因其重要性和实用性而成为研究的核心。本文研究了简单连通图的测地数,它是简单连通图的一个整体测度,它属于路径覆盖问题:什么是顶点的最小基数集,使得它的元素之间的所有最短路径覆盖图的每个顶点。受最近文献中精确0-1整数线性规划形式的启发,我们提出了一种新的方法,以算法的方式获得大地数的上界。这些算法的效率证明了一个结构不同的图形的集合。

英文摘要:

Graph theoretical problems based on shortest paths are at the core of research due to their theoretical importance and applicability. This paper deals with the geodetic number which is a global measure for simple connected graphs and it belongs to the path covering problems: what is the minimal-cardinality set of vertices, such that all shortest paths between its elements cover every vertex of the graph. Inspired by the exact 0-1 integer linear programming formalism from the recent literature, we propose a new methods to obtain upper bounds for the geodetic number in an algorithmic way. The efficiency of these algorithms are demonstrated on a collection of structurally different graphs.
