Trémaux树与平面性

Trémaux trees and planarity

Hubert De Fraysseix, Patrice Ossona De Mendez, Pierre Rosenstiehl

摘要:

我们提出了一个简化版本的基于DFS的左-右平面性测试和嵌入算法,该算法在Pigale中实现,被认为是最快实现的算法[J.M. Boyer,P.F. Cortese,M. Patrignani和G.迪·巴蒂斯塔别再管你的P和Q了:实现快速简单的基于DFS的平面化和嵌入算法。在Graph Drawing中,计算机科学讲义第2912卷,第25-36页。Springer,2004.]。我们在这里给一个简单的充分理由的算法,基于初步扩展的DFS树的拓扑性质的研究。

英文摘要:

We present a simplified version of the DFS-based Left-Right planarity testing and embedding algorithm implemented in Pigale which has been considered as the fastest implemented one [J.M. Boyer, P.F. Cortese, M. Patrignani, and G. Di Battista. Stop minding your P's and Q's: implementing fast and simple DFS-based planarity and embedding algorithm. In Graph Drawing, volume 2912 of Lecture Notes in Computer Science, pages 25-36. Springer, 2004.]. We give here a simple full justification of the algorithm, based on a preliminary extended study of topological properties of DFS trees.
