WebSep 22, 2024 · In a graph of strongly connected components, mother vertices are always vertices of the source components in the component graph. The idea is based on the below fact: If there exists a mother vertex (or vertices), then one of the mother vertices is the last finished vertex in DFS. (Or a mother vertex has the maximum finish time in DFS traversal).
