Bounded tolerance graphs were introduced in Golumbic and Monma (Congr. Numer. 35 (1982) 321–331) and Golumbic et al. (Discrete Appl. Math. 9 (1984) 157–170) as a generalization of interval graphs. Several variations of bounded tolerance graphs have been studied, including bounded bitolerance graphs. In this paper, we introduce directed versions of the… CONTINUE READING
