WebThe DFS algorithm’s space complexity is O(V), excluding the memory consumed by the graph representation, where V is the number of nodes in the graph. Note: Graph representation takes O(V+E) memory when using adjacency list and O(V2) memory when using adjacency matrix WebBreadth-first search ( BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level.

WebSpace Complexity: DFS algorithm needs to store only single path from the root node, hence space complexity of DFS is equivalent to the size of the fringe set, which is O (bm). Optimal: DFS search algorithm is non-optimal, as it may generate a large number of steps or high cost to reach to the goal node. 3.
