Tournament Graphs: Properties and Algorithms
Definition of Tournament Graphs
A directed graph \(G\) without self-loops is called a tournament if there exists exactly one directed edge between every pair of distinct vertices.
Strong Connectivity in Tournament Graphs
After contracting strongly connected components in a tournament graph \(G = (V, E)\), the result is a directed path.
Let’s as ...
