Path-based Strong Component Algorithm
In graph theory, the strongly connected components of a directed graph may be found using an algorithm that uses depth-first search in combination with two stacks, one to keep track of the vertices in the current component and the second to keep track of the current search path. Versions of this algorithm have been proposed by , , , , and ; of these, Dijkstra's version was the first to achieve linear time.History of Path-based DFS for Strong Components

Description

The algorithm performs a depth-first search of the given graph ''G'', maintaining as it does two stacks ''S'' and ''P'' (in addition to the normal call stack for a recursive function). Stack ''S'' contains all the vertices that have not yet been assigned to a strongly connected compone ...
