WebDijkstra's algorithm is used to find the shortest distance between the nodes of a graph. We can use this algorithm for both directed and undirected graphs, but it won't work with negative edge weights. We can further optimize our implementation by using a min-heap or a priority queue to find the closest node. ← Java Type Casting. kearneys coaches corkThe emphasis in this article is the shortest path problem (SPP), being one of the fundamental theoretic problems known in graph theory, and how the Dijkstra algorithmcan be used to solve it.
