WebJul 29, 2024 · Topological sort is an algorithm that takes a directed acyclic graph and returns the sequence of nodes where every node will appear before other nodes that it points to. Just to remind, a directed acyclic graph (DAG) is the graph having directed edges from one node to another but does not contain any directed cycle. WebA topological sort of a directed acyclic graph G = ( V, E) is a linear ordering of all its vertices such that if G contains an edge ( u, v), then u appears before v in the ordering. It is worth noting that if the graph contains a cycle, then no linear ordering is possible. It is useful to view a topological sort of a graph as an ordering of its ...
