燃烧图的新算法

New heuristics for burning graphs

摘要:

图燃烧和图G的燃烧数($bn(G)$)的概念是最近提出的[1]。图燃烧模型在离散时间步长中的图中传染(火)的传播。$bn(G)$是刻录图形$G$所需的最短时间。该问题是NP完全的。在本文中,我们开发了第一个算法来解决一般(连通)图的问题。为了测试算法的性能,我们将其应用于一些已知燃烧数的图类,如theta图,我们测试了我们的算法在DIMACS和BHOSLIB,这是已知的NP-难问题的图论基准。我们还改进了一般图的燃烧数的上界,根据它们到簇的距离。然后,我们生成了一个数据集的2000个随机图与已知的距离聚类和测试我们的算法对他们。

英文摘要:

The concept of graph burning and burning number ($bn(G)$) of a graph G was introduced recently [1]. Graph burning models the spread of contagion (fire) in a graph in discrete time steps. $bn(G)$ is the minimum time needed to burn a graph $G$.The problem is NP-complete. In this paper, we develop first heuristics to solve the problem in general (connected) graphs. In order to test the performance of our algorithms, we applied them on some graph classes with known burning number such as theta graphs, we tested our algorithms on DIMACS and BHOSLIB that are known benchmarks for NP-hard problems in graph theory. We also improved the upper bound for burning number on general graphs in terms of their distance to cluster. Then we generated a data set of 2000 random graphs with known distance to cluster and tested our heuristics on them.
