计算树和有界树宽图的Fréchet距离

Computing the Fréchet distance of trees and graphs of bounded tree width

Maike Buchin, Amer Krivošija, Alexander Neuhaus

摘要:

我们给出了计算树和图的Fréchet距离的算法,树的宽度有界。我们的算法运行在$O(n^2)$时间为有界度的树,和$O(n^2\sqrt{n \log n})$时间为任意度的树。对于有界树宽的图,我们证明了可以在FPT(固定参数易处理)时间内计算Fréchet距离。

英文摘要:

We give algorithms to compute the Fréchet distance of trees and graphs with bounded tree width. Our algorithms run in $O(n^2)$ time for trees of bounded degree, and $O(n^2\sqrt{n \log n})$ time for trees of arbitrary degree. For graphs of bounded tree width we show one can compute the Fréchet distance in FPT (fixed parameter tractable) time.
