The maximum number of times the decrease key operation performed in Dijkstra's algorithm will be equal to

b) Single source shortest path

Explanation:

These are the options for the question

a) All pair shortest path

b) Single source shortest path

c) Network flow

d) Sorting

Dijkstra's algorithm is algorithm by

Edsger Dijkstra arround the year 1956, this algorithm determine the shortest path, this path could be between two nodes/vertice of a graph.

The steps involves are;

✓setting up of the distances base on the algorithm.

✓ calculation of the first vertice up to vertice adjacent to it

✓The shortest path result.

It should be noted that maximum number of times the decrease key operation performed in Dijkstra's algorithm will be equal to Single source shortest path.
