Which algorithm is used to find all pairs of shortest paths in a graph?
All-Pairs Shortest Paths: The Floyd-Warshall algorithm finds the shortest paths for all pairs of nodes in the graph, not just from one node to all others. This means that after running the algorithm, you know the shortest path between any two nodes in the graph.
What is a parallel algorithm in analysis and design of algorithms?
A parallel algorithm is cost optimal when its cost matches the run time of the best known sequential algorithm Ts for the same problem. The speed up S offered by a parallel algorithm is simply the ratio of the run time of the best known sequential algorithm to that of the parallel algorithm.
Which of these is the algorithm used for solving the shortest path problem?
Explanation: Dijkstra's algorithm is used to solve the single source shortest path problem. Key points for this: It is used for both directed and undirected graphs.
