- Dijkstras algorithm - Wikipedia
Dijkstra's algorithm ( ˈdaɪkstrəz DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, a road network It was conceived by computer scientist Edsger W Dijkstra in 1956 and published three years later [4][5][6] Dijkstra's algorithm finds the shortest path from a given source node to every other node [7]: 196
- Shortest path problem - Wikipedia
Several well-known algorithms exist for solving this problem and its variants Dijkstra's algorithm solves the single-source shortest path problem with only non-negative edge weights Bellman–Ford algorithm solves the single-source problem if edge weights may be negative A* search algorithm solves for single-pair shortest path using heuristics to try to speed up the search Floyd–Warshall
- Optimal substructure - Wikipedia
Typically, a greedy algorithm is used to solve a problem with optimal substructure if it can be proven by induction that this is optimal at each step [1] Otherwise, provided the problem exhibits overlapping subproblems as well, divide-and-conquer methods or dynamic programming may be used
- Shortest-path tree - Wikipedia
In connected graphs where shortest paths are well-defined (i e where there are no negative-length cycles), we may construct a shortest-path tree using the following algorithm: Compute dist (u), the shortest-path distance from root v to vertex u in G using Dijkstra's algorithm or Bellman–Ford algorithm
- Parallel all-pairs shortest path algorithm - Wikipedia
Dijkstra algorithm The Dijkstra algorithm originally was proposed as a solver for the single-source-shortest-paths problem However, the algorithm can easily be used for solving the All-Pair-Shortest-Paths problem by executing the Single-Source variant with each node in the role of the root node

- Greedy algorithm - Wikipedia
Greedy algorithm Greedy algorithms determine the minimum number of coins to give while making change These are the steps most people would take to emulate a greedy algorithm to represent 36 cents using only coins with values {1, 5, 10, 20} The coin of the highest value, less than the remaining change owed, is the local optimum
- Prims algorithm - Wikipedia
A demo for Prim's algorithm based on Euclidean distance In computer science, Prim's algorithm is a greedy algorithm that finds a minimum spanning tree for a weighted undirected graph This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized
