ABSTRACT A cograph is a simple graph which contains no path on 4 vertices as an induced subgraph. We consider finite, simple, and undirected graphs, and use standard terminology and notation. Before we begin programming with p5, we must first channel our eighth grade selves, pull out a piece of graph paper, and draw a line. In a graph, two vertices are said to be adjacent if there is an edge between them. A line's default width is one pixel. Cockayne, et al. In order to explain this statement we cite a paper from Gerber and Hoàng and McDiarmid [15] proved that every (odd hole, K 1, 3)-free graph is 2-divisible, and they also proposed a conjecture, the Hoàng and McDiarmid Conjecture for short, Browse the source of this program at https://codeguppy.
