2. Dijkstra's algorithm - Wikipedia

   en.wikipedia.org/wiki/Dijkstra's_algorithm

   Dijkstra's algorithm to find the shortest path between a and b. It picks the unvisited vertex with the lowest distance, calculates the distance through it to each unvisited neighbor, and updates the neighbor's distance if smaller. Mark visited (set to red) when done with neighbors. Dijkstra's algorithm (/ ˈdaɪkstrəz / DYKE-strəz) is an ...

3. Pathfinding - Wikipedia

   en.wikipedia.org/wiki/Pathfinding

   Pathfinding. Pathfinding or pathing is the search, by a computer application, for the shortest route between two points. It is a more practical variant on solving mazes. This field of research is based heavily on Dijkstra's algorithm for finding the shortest path on a weighted graph.

4. Shortest path problem - Wikipedia

   en.wikipedia.org/wiki/Shortest_path_problem

   Shortest path algorithms are applied to automatically find directions between physical locations, such as driving directions on web mapping websites like MapQuest or Google Maps.

5. k shortest path routing - Wikipedia

   en.wikipedia.org/wiki/K_shortest_path_routing

   The k shortest path routing problem is a generalization of the shortest path routing problem in a given network. It asks not only about a shortest path but also about next k−1 shortest paths (which may be longer than the shortest path).

6. A* search algorithm - Wikipedia

   en.wikipedia.org/wiki/A*_search_algorithm

   A* (pronounced "A-star") is a graph traversal and pathfinding algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. [1] Given a weighted graph, a source node and a goal node, the algorithm finds the shortest path (with respect to the given weights) from source to goal.

7. Chinese postman problem - Wikipedia

   en.wikipedia.org/wiki/Chinese_postman_problem

   In graph theory, a branch of mathematics and computer science, Guan's route problem, the Chinese postman problem, postman tour or route inspection problem is to find a shortest closed path or circuit that visits every edge of an (connected) undirected graph at least once. When the graph has an Eulerian circuit (a closed walk that covers every edge once), that circuit is an optimal solution ...
