Web1016 HAROLD N. GABOWAND ROBERT E. TARJAN A matching in a graph is a set of vertex-disjoint edges. Thus a vertex v is in at most one matched edge vvr; v is the mate of v. Afree vertex has no mate. A maximum cardinality matching has the greatest number of edges possible; a perfect matching has no free vertices (and is clearly maximum cardinality). An … Websearch of an undirected graph (Algorithm 5.2 of [1]). Therefore, the running time of UH, FOREST can be written as O(m 2i) at the i-th iteration, where m is the number of edges at the rst call. To sum up, the total running time of this algorithm is: O(m+ m 2 + m 2 + m 4 + m 8 + :::+ 1) = O(m) Example The following example shows that how the ...

WebA good diff algorithm finds the shortest script, using CPU and memory sparingly. There may be applications in which the "best" edition script, subjectively speaking, may not be the shortest one — in particular when a human is going to read the script.

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.
