Strict 2-threshold graphs
A graph is a strict 2-threshold graph if its edge set can be partitioned into two threshold graphs \(T_ 1\) and \(T_ 2\) so that any triangle in G appears in either \(T_ 1\) or \(T_ 2\). The authors give a polynomial- time algorithm for determining when G is a strict 2-threshold graph.
