Data Source and Methodology

All calculations are based on Dijkstra's Algorithm as articulated in standard graph theory textbooks. Learn more about the algorithm here. All calculations strictly follow these formulas and data.

The Formula Explained

Dijkstra's Algorithm is used to find the shortest path between nodes in a graph. It uses a priority queue to explore the nearest unvisited node and updates paths to neighboring nodes.

Glossary of Terms

How It Works: A Step-by-Step Example

Assume a graph where node 1 is connected to node 2 with a weight of 10, and node 2 is connected to node 3 with a weight of 5. The shortest path from node 1 to node 3 is 1 -> 2 -> 3 with a total cost of 15.

Frequently Asked Questions (FAQ)

What is Dijkstra's Algorithm?

Dijkstra's Algorithm finds the shortest path between nodes in a graph, which may represent, for example, road networks.

Is Dijkstra's Algorithm always the best choice?

It's highly efficient for graphs with non-negative weights, but other algorithms like A* might be better for specific uses.

Can you use Dijkstra's Algorithm on a directed graph?

Yes, it can be used on both directed and undirected graphs.

Does Dijkstra's Algorithm handle negative weights?

No, it assumes all edge weights are non-negative.

How does Dijkstra's Algorithm compare to Bellman-Ford?

Bellman-Ford can handle negative weights, but Dijkstra's is more efficient for graphs with non-negative weights.
