Depth first search for graphs

WebReading time: 15 minutes Coding time: 5 minutes. Depth-first search (DFS) algorithm is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking. WebOct 10, 2024 · There are two basic types of graph search algorithms: depth-first and breadth-first. The former type of algorithm travels from a starting node to some end …

The algorithm starts at the root node and explores each neighboring node as far as possible. The moment it reaches a dead-end, it backtracks until it finds a new, undiscovered node, then traverses from that node to find more undiscovered nodes. christoph sembdner guitar
