Suppose we run Dijkstra’s single source shortest-path algorithm on the following edge weighted directed graph with vertex A as the source. What is the order of the vertices in which the shortest path is found by the algorithm?

                            image

(A) A,B,C,D,F,E

(B) A,B,C,D,E,F

(C) A,B,D,C,E,F

(D) A,B,C,E,D,F

Best answer

From A, we'll choose B.

In the next we choose min(A+3,B+3) which is C and so on.

Dijkstra algorithm will visit the nodes in the following order: A,B,C,D,F,E

The answer is A.
