Study Notes
Dijkstra's Algorithm
- Dijkstra's algorithm is used to find the shortest paths between nodes in a weighted graph.
- Edsger W. Dijkstra conceived Dijkstra's algorithm.
Functionality of Dijkstra's Algorithm
- When a single source node is fixed, Dijkstra's algorithm finds the shortest paths from the source node to all other nodes in the graph.
- The algorithm produces a shortest-path tree, which is a subgraph that contains the shortest paths from the source node to all other nodes.
Representation of Graph
- The graph can represent various systems, such as transportation networks, communication networks, or social networks.
Variants of Dijkstra's Algorithm
- A variant of Dijkstra's algorithm, known as the single-pair shortest path problem, finds the shortest path between two given nodes.
Edge Costs
- The costs of edge paths in the graph can represent various metrics, such as distance, time, or cost.
History of Dijkstra's Algorithm
- Dijkstra's algorithm was published in 1959.
