What is the greedy criterion of the shortest path algorithm?
By greedy criterion A [v*] + lv*w* <= A [y] + lyz <= length of P. The first part is actually A [w*], our chosen path. In other words, A [w*] is indeed the shortest path. The correctness of Dijkstra shortest-path algorithm is proved.
What is the algorithm used to find shortest paths from source to all vertices in a?
Given a graph and a source vertex in the graph, find shortest paths from source to all vertices in the given graph. Dijkstra’s algorithm is very similar to Prim’s algorithm for minimum spanning tree.
What is the best way to make a greedy algorithm?
To make a greedy algorithm, identify an optimal substructure or subproblem in the problem. Then, determine what the solution will include (for example, the largest sum, the shortest path, etc.). Create some sort of iterative way to go through all of the subproblems and build a solution.
What is used to find the shortest path through a graph?
Greedy algorithms are quite successful in some problems, such as Huffman encoding which is used to compress data, or Dijkstra's algorithm, which is used to find the shortest path through a graph. However, in many problems, a greedy strategy does not produce an optimal solution.
