 Perfectly orderable graph

A **perfectly orderable graph** is a type of graph that can be represented in such a way that its vertices can be linearly ordered such that for every edge connecting two vertices \( u \) and \( v \), one of the following conditions holds: \( u \) comes before \( v \) in the order or \( v \) comes before \( u \), and the two vertices do not share any common neighbors that come in between them in the order.
