Overview[edit] The basic idea of the algorithm is this: a depth-first search begins from an arbitrary start node (and subsequent depth-first searches are conducted on any nodes that have not yet been found). As usual with depth-first search, the search visits every node of the graph exactly once, declining to revisit any node that has already been explored. Thus, the collection of search trees is a spanning forest of the graph. The strongly connected components will be recovered as certain subtrees of this forest. Stack invariant[edit] At the end of the call that explores v and its descendants, we know whether v itself has a path to any node earlier on the stack. Bookkeeping[edit] Each node v is assigned a unique integer v.index, which numbers the nodes consecutively in the order in which they are discovered.
The algorithm in pseudocode[edit] The index variable is the depth-first search node number counter. Remarks[edit] References[edit] External links[edit] Home. Home. Now in IEEE Xplore: The latest issue of IEEE Spectrum looking at the impact of lasers on motion pictures This issue explores how lasers will trigger the next great revolution in motion pictures. More and more, people are watching movies on their laptops, tablets, and smartphones. In wealthy countries, middle-class homes are now typically outfitted with huge flat-panel TVs and powerful surround-sound audio systems. The upshot is that for many people, a trip to a movie theater is becoming a rare event, if not an increasingly distant memory. Learn how laser-based projection technology will make cinema screens bigger and brighter. » View the issue in IEEE Xplore. Journals / Find Research & Publications / IOL Home - INFORMS.org.
