[HTML][HTML] A simple linear time algorithm for cograph recognition

M Habib, C Paul - Discrete Applied Mathematics, 2005 - Elsevier
In this paper, we describe a new simple linear time algorithm to recognize cographs.
Cographs are exactly the P4-free graphs (where P4 denotes the path with 4 vertices). The …
