We consider the following tree-matching problem: Given labeled, ordered trees P and T , can P be obtained from T by deleting nodes? Deleting a node v entails removing all edges incident to v and, if v has a parent u, replacing the edges from u to v by edges from u to the children of v. The existing algorithm for this problem needs O(|T || leaves(P )|) time and O(| leaves(P )|min{DT , | leaves(T )|}) space, where leaves(P ) (leaves(T )) stands for the number of the leaves of P(T ), and DT for… CONTINUE READING
