Bread First Search (BFS): We scan through the tree level by level, following the order of … 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 ...
