摘要

Shields-Harary数字是一类图形参数，用于衡量图形的某种鲁棒性，可以将其视为一个强化油藏网络，参考给定的成本函数。我们证明了关于凹连续代价函数的shield - harary数的一个结果，它简化了某些图类(包括由两个相交团构成的图和完全多部图)的这些数的计算。

SHIELDS-HARARY NUMBERS OF GRAPHS WITH RESPECT TO CONTINUOUS CONCAVE COST FUNCTIONS

The Shields-Harary numbers are a class of graph parameters that measure a certain kind of robustness of a graph, thought of as a network of fortified reservoirs, with reference to a given cost function. We prove a result about the Shields-Harary numbers with respect to concave continuous cost functions which will simplify the calculation of these numbers for certain classes of graphs, including graphs formed by two intersecting cliques, and complete multipartite graphs.
