The authors deal with poset \(P=(X,\prec)\) as a unit OC interval order and give a forbidden poset characterization of the class of unit OC interval orders and an efficient algorithm for recognizing the class. The algorithm takes a poset \(P\) as the input. It produces a representation or returns a forbidden poset induced in \(P\).
