WebJul 6, 2015 · To keep track of depth while conducting a breadth first search, we simply need to reverse this calculation. Whereas the above formula allows us to solve for N given d, we actually want to solve for d given N. For instance, say we're evaluating the 5th node. To figure out what depth the 5th node is on, we take the following equation: 2^d - 1 = 5 ... WebA* Search. A* Search is an informed best-first search algorithm that efficiently determines the lowest cost path between any two nodes in a directed weighted graph with non-negative edge weights. This algorithm is a variant of Dijkstra’s algorithm. A slight difference arises from the fact that an evaluation function is used to determine which ...
