树的广义LR-图

Generalized LR-drawings of trees

Therese Biedl, Giuseppe Liotta, Jayson Lynch, Fabrizio Montecchiani

摘要:

LR绘制方法是一种绘制有序有根二叉树的方法,该方法基于在垂直线上绘制一条根到叶的路径,并在左侧和右侧附加递归获得的子树的绘图。本文研究如何将这种作图方法推广到高元数树。我们首先证明(经过一些仔细的修改),证明存在一个特殊的根到叶路径转移到树的更高的arity。然后,我们使用这样的路径,以获得广义LR-图的任意arity的树。

英文摘要:

The LR-drawing-method is a method of drawing an ordered rooted binary tree based on drawing one root-to-leaf path on a vertical line and attaching recursively obtained drawings of the subtrees on the left and right. In this paper, we study how to generalize this drawing-method to trees of higher arity. We first prove that (with some careful modifications) the proof of existence of a special root-to-leaf path transfers to trees of higher arity. Then we use such paths to obtain generalized LR-drawings of trees of arbitrary arity.
