O(# vertices + # edges)
The space complexity of Depth First Search (DFS) algorithm is O(bd), where b is the branching factor and d is the maximum depth of the search tree.

The space complexity of the breadth-first search algorithm is O(V), where V is the number of vertices in the graph being traversed.
O(N-1)
The space complexity of the Breadth-First Search (BFS) algorithm is O(V), where V is the number of vertices in the graph being traversed.
The space complexity of the Breadth-First Search (BFS) algorithm is O(V), where V is the number of vertices in the graph being traversed.
Both algoritms can be build very similary. The difference between breadth-first search and depth-first search is order in which elements ar added to OPEN list. In breadth-first search new nodes are appended to the end of OPEN list In depth-first search new nodes are inserted in the begining of OPEN list
Iterative deepening effectively performs a breadth-first search in a way that requires much less memory than breadth-first search does. So before explaining the advantage of iterative deepening over depth-first, its important to understand the difference between breadth-first and depth-first search. Depth first explores down the tree first while breadth-first explores all nodes on the first level, then the second level, then the third level, and so on. Breadth-first search is ideal in situations where the answer is near the top of the tree and Depth-first search works well when the goal node is near the bottom of the tree. Depth-first search has much lower memory requirements. Iterative deepening works by running depth-first search repeatedly with a growing constraint on how deep to explore the tree. This gives you you a search that is effectively breadth-first with the low memory requirements of depth-first search. Different applications call for different types of search, so there's not one that is always better than any other.
