Basically, there are two algorithms used for topological sort, described on Wikipedia. Kahn's algorithm works with any graph traversal, including BFS or DFS. Tarjan's algorithm, which is now the most well known, uses a "reverse DFS postorder" traversal of the graph. Postorder means you add a node to the list after visiting its children.
