Key Concepts

Depth-first search (DFS)

DFS is a graph traversal technique that explores as far as possible along each branch before backtracking. It systematically visits all the vertices in a graph by moving from one vertex to its adjacent vertices, and it is commonly used in tasks such as connectivity testing, cycle detection, and path finding.

DFS tree

A DFS tree is the spanning tree produced by executing a depth-first search on a graph. In this tree, each vertex (except the starting vertex) is reached via a unique parent from which it was first discovered, thereby encapsulating the exploration order of the DFS algorithm.

DF-algorithm

The DF-algorithm is a systematic procedure based on depth-first search that involves the exploration of graph vertices in a specific order. It typically includes steps like marking visited nodes, backtracking, and recording discovery order, which are critical in forming the DFS tree.

Depth-first numbering

Depth-first numbering assigns a unique number to each vertex in the order it is first encountered during a DFS traversal. This numerical labeling is useful for analyzing the structure of the DFS tree, such as identifying entry and exit times in various graph algorithms.
