设G是一个无向图,Γ是它在平面上的图. G中的每个顶点都有一个指定大小的标签。在本文中,我们考虑的问题,将最大数量的顶点标签在r中,以这样的方式,他们不重叠任何顶点,边或其他标签。通过改进Kakoulis-Tollis算法的几个部分,标记图形特征,我们提出了一个启发式算法解决这个问题。实验结果表明,我们的算法可以放置更多的标签比以前的算法。
Let G be an undirected graph and let Γ be its drawing on a plane. Each vertex in G has a label with a specified size. In this paper, we consider the problem of placing the maximum number of vertex labels in r in such a way that they do not overlap any vertices, edges or other labels. By refining several portions of the Kakoulis-Tollis algorithm for labeling graphical features, we present a heuristic algorithm for this problem. Experimental results show that our algorithm can place more labels than previous algorithms.
