WebDepth-First Search - Theory. Depth-First Search (DFS) is an algorithm used to traverse or locate a target node in a graph or tree data structure. It priorities depth and searches along one branch, as far as it can go - until the end of that branch. Once there, it backtracks to the first possible divergence from that branch, and searches until ... Web2 Lecture 10: Depth-First Search.
