SpletRun BFS twice, from both v and w, as a hint. Find the shortest ancestral route between v and w given a DAG and two nodes, v and w. A shared progenitor x, the shortest route from v to x, and the shortest route from w to x make up an ancestral path between v and w. The ancestral route whose overall length is minimised is the smallest ancestral path. dundee packing house
