Depth first search notes
Depth first search utilizes backtracking and recursion to explore each node of a tree, or each vertex of a graph, exactly once.
On a graph, depth-first search is a crucial building block of several algorithms related to connectivity, such as finding cycles, determining of two vertices are connected, and constructing spanning trees.
For an example of depth-first search on a graph, see traveling salesperson problem page.
