Arrangeable graph — аранжируемый граф.
A cf-graph is called arrangeable if its arrangementexists and nonarrangeable otherwise.
Every arc of an arrangeable graph [math]\displaystyle{ G }[/math] is either forward or backward arc. An arc of [math]\displaystyle{ G }[/math] is called a backward arc if it is an [math]\displaystyle{ F }[/math]-inverse arc for an arrangement of [math]\displaystyle{ G }[/math] and a forward arc if it is an [math]\displaystyle{ F }[/math]-direct arc for an arrangement of [math]\displaystyle{ G }[/math].
A depth of an arrangeable graph [math]\displaystyle{ G }[/math] is defined as the depth of an arrangement of [math]\displaystyle{ G }[/math].
