Topological sort bfs. Nov 2, 2025 · Kahn’s Algorithm is a Breadth-First Search (BFS) based approach for performing Topological Sorting on a Directed Acyclic Graph (DAG). Feb 16, 2017 · Yes, you can do topological sorting using BFS. Dec 20, 2025 · Topological Sort using BFS (Kahn’s Algorithm) works by repeatedly selecting vertices with in-degree zero (no dependencies), adding them to the result, and reducing the in-degree of their adjacent vertices. . Topological sorting for Directed Acyclic Graph (DAG) is a linear ordering of vertices such that for every directed edge u->v, vertex u comes before v in the ordering. And consequently in BFS implementation we don’t have to reverse the order in which we get the vertices, since we get the vertices in order of the topological ordering. Detailed solution for Topological Sort (BFS) - Problem statement: Given a graph, find the topological order for the given graph. Topological sort: The linear ordering of nodes/vertices such that if there exists an edge between 2 nodes u,v then In BFS implementation of the Topological sort we do the opposite: We look for for edges with no inbound edges. Topological Sorting for a graph is not possible if the graph is not a DAG. Actually I remembered once my teacher told me that if the problem can be solved by BFS, never choose to solve it by DFS.
