摘要：
We describe a tree difference and edit sequence algorithm with expected sequential execution time O(nlogIogn) and expected parallel execution time O(logn), for trees of size n. The algorithm assumes unique labels and permits operations only on leaves and frontier subtrees. Despite this assumption, its application domain includes structured text and hypertext, and it is much faster than existing algorithms based on dynamic programming.
