Abstract

Motivated by recent applications of dominator computations we consider the problem of dynamically maintaining the dominators of a flowgraph through a sequence of insertions and deletions of edges. We present new algorithms and efficient implementations of existing algorithms and exhibit their efficiency in practice.
