WebNov 4, 2024 · The heuristic value has an important role in the efficiency of the A* algorithm. To find the best solution, you might have to use different heuristic functions according to the type of the problem. However, the creation of these functions is a difficult task, and this is the basic problem we face in AI. What is a Heuristic Function? WebIt achieves this by introducing a heuristic element to help decide the next node to consider as it moves along the path. You can read more about heuristics in the topic on complexity. Dijkstra’s algorithm finds the shortest path between the start node and all other nodes.
