Introduction

Along with breadth-first search, depth-first search is one of the two main methods to walk through a graph. This approach though is different. Breadth-first search (BFS) looks pretty much like starting from a vertex and expanding the searching process level by level. This means that first we get some information of all the successors of the given node and then we go further with the next level. In other words BFS is like a wave. Depth-first search is based on a different approach, which can be very useful in some specific algorithms.

Both methods can be useful in solving different tasks. Continue reading Computer Algorithms: Graph Depth-First Search →
