In computer science, Tarjan's off-line lowest common ancestors algorithm is an algorithm for computing lowest common ancestors for pairs of nodes in a tree, based on the union-find data structure. The lowest common ancestor of two nodes d and e in a rooted tree T is the node g that is an ancestor of both d and e and that has the greatest depth ...
For example, in a program, two variables may be defined thus (in pseudocode): data_item x := 1 data_item y := 0 swap (x, y); After swap() is performed, x will contain the value 0 and y will contain 1; their values have been exchanged.
In this example we assume that DijkstraSSSP takes the graph and the root node as input. The result of the execution in turn is the distancelist d v {\displaystyle d_{v}} . In d v {\displaystyle d_{v}} , the i {\displaystyle i} -th element stores the distance from the root node v {\displaystyle v} to the node i {\displaystyle i} .
Using the XOR swap algorithm to exchange nibbles between variables without the use of temporary storage. In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required.
Example graph. Following is a step by step description of the algorithm execution for a small example graph. The source vertex is the vertex A and is equal to 3. At the beginning of the algorithm, all vertices except for the source vertex A have infinite tentative distances.

Average path length, or average shortest path length is a concept in network topology that is defined as the average number of steps along the shortest paths for all possible pairs of network nodes. It is a measure of the efficiency of information or mass transport on a network.
Thus, a combinatorial technique for picking test cases like all-pairs testing is a useful cost-benefit compromise that enables a significant reduction in the number of test cases without drastically compromising functional coverage. [5] More rigorously, if we assume that a test case has parameters given in a set {} = {,,...
