Several algorithms based on depth-first search compute strongly connected components in linear time. • Kosaraju's algorithm uses two passes of depth-first search. The first, in the original graph, is used to choose the order in which the outer loop of the second depth-first search tests vertices for having been visited already and recursively explores them if not. The second depth-first search … WebApr 8, 2024 · This informs the SCC and the pass manager that the specified Old node has been deleted, and New is to be used in its place.

WebDec 8, 2024 · 1 Answer. The first thing that you should notice is that the set of strongly connected components is the same for a graph and its reverse. In fact, the algorithm actually finds the set of strongly connected components in the reversed graph, not the original (but it's alright, because both graphs have the same SCC).
