摘要
In a directed acyclic graph G = (V, E) with a single source s, the nearest common dominator for a set of nodes U ⊂ V is the node d closest to U such that every path from s to any node in U goes through d. The distance between any node w and U is defined as the number of arcs in a shortest path from w to any node in U. We develop an optimal algorithm for finding the nearest common dominator d for U, which runs in time proportional to the number of arcs in between d and U. © 1992.
