## Basic Graph Theory and Search

DFS (Depth First Search) basic concept Depth First Search An algorithm for traversing or searching a tree or graph. Traverse the nodes of the tree along the depth of the tree, searching the branches of the tree as deep as possible. When the edge of node v has been explored or the node does not meet the conditions during the search, the se ...
