Can BFS be used for topological sort?
Yes, you can do topological sorting using BFS. Actually I remembered once my teacher told me that if the problem can be solved by BFS, never choose to solve it by DFS. Because the logic for BFS is simpler than DFS, most of the time you will always want a straightforward solution to a problem.
What is topological sorting problem?
In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. Topological sorting has many applications especially in ranking problems such as feedback arc set.
What is a valid topological sort?
Precisely, a topological sort is a graph traversal in which each node v is visited only after all its dependencies are visited. A topological ordering is possible if and only if the graph has no directed cycles, that is, if it is a directed acyclic graph (DAG).
What problems is topological sort useful for?
Topological sorting has many applications especially in ranking problems such as feedback arc set . The canonical application of topological sorting is in scheduling a sequence of jobs or tasks based on their dependencies.

Is topological sorting trying to sort vertices or edges?
Topological sorting sorts vertices in such a way that every directed edge of the graph has the same direction. Topological ordering is only possible for the Directed Acyclic Graphs (i.e., DAG).
What is a topological order?
Topological order. In physics, topological order is a kind of order in the zero-temperature phase of matter (also known as quantum matter). Macroscopically, topological order is defined and described by robust ground state degeneracy and quantized non- Abelian geometric phases of degenerate ground states.
