WebSubtrees, forests, and graphs • A subtree rooted at u is the tree formed from u and all its descendants. • A forest is a (possibly empty) set of trees. The set of subtrees rooted at the children of r form a forest. • As we’ve deﬁned them, trees are not a special case of graphs:-Our trees are oriented (there is a root which implicitly deﬁnes directions on the edges).
