Topological sorting orders vertices in a directed acyclic graph from "summary" of Data Structures and Algorithms in Python by Michael T. Goodrich,Roberto Tamassia,Michael H. Goldwasser
Topological sorting is a crucial concept in graph theory, particularly when dealing with directed acyclic graphs. In such graphs, edges have a specified direction and do not form any cycles. The primary goal of topological sorting is to order the vertices in a way that respects the edge directions, ensuring that if there is an edge from vertex u to vertex v, then u comes before v in the ordering. By performing topological sorting on a directed acyclic graph, we can determine a linear ordering of the vertices that satisfies the constraints imposed by the edges. This ordering is significant in various applications, such as task scheduling, dependency resolution, and symbolic reasoning. The algorithm for topological sorting works by repeatedly selecting a vertex with no incoming edges, removing it from the graph, and adding it to the sorted order. This...
