"Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes discovered so far along a specified branch … " - Dfs tree algorithm

However, if you keep track of visited nodes, it turns to be complete(in graph search). let's be clear about what completeness means. If an algorithm is complete, it means that if at least one solution exists then the algorithm is guaranteed to find a solution in a finite amount of time.

WebA more elegant algorithm always starts at simple ob-servations. Suppose we run DFS on , we get a DFS tree. If the root has two or more children, it is an ar-ticulation point. Moreover, a leaf is not an articulation point. Some parts of the tree have edges that ’climbs’ to the upper part of the tree , while other does not have this edge. 14
