论文摘要
我们提供算法来计算树木和有界树宽度的树木的距离。我们的算法以$ o(n^2)为有限度的树和$ o(n^2 \ sqrt {n \ log n})$的时间运行。对于有界树宽度的图形,我们显示可以在FPT(固定参数可拖动)时间中计算Fréchet距离。
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.
