Dfs tree algorithm

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 … WebAs stated on their main website, the "DIMACS Implementation Challenges address questions of determining realistic algorithm performance where worst case analysis is …

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.
