Two primary problems of pathfinding are (1) to find a path between two nodes in a graph and (2) the shortest path problem-to find the optimal shortest path. An analogy would be a person walking across a room rather than examining every possible route in advance, the person would generally walk in the direction of the destination and only deviate from the path to avoid an obstruction, and make deviations as minor as possible. Although graph searching methods such as a breadth-first search would find a route if given enough time, other methods, which "explore" the graph, would tend to reach the destination sooner.

Pathfinding is closely related to the shortest path problem, within graph theory, which examines how to identify the path that best meets some criteria (shortest, cheapest, fastest, etc) between two points in a large network.Īt its core, a pathfinding method searches a graph by starting at one vertex and exploring adjacent nodes until the destination node is reached, generally with the intent of finding the cheapest route. This field of research is based heavily on Dijkstra's algorithm for finding the shortest path on a weighted graph.
It is a more practical variant on solving mazes. Pathfinding or pathing is the plotting, by a computer application, of the shortest route between two points. Equivalent paths between A and B in a 2D environment
