COMMENTS ON A PAPER BY W. ROTHFARB, N. P. SCHEIN, AND I. T. FRISCH: 'COMMON TERMINAL MULTICOMMODITY FLOW'

Abstract : The article 'Common Terminal Multicommodity Flow,' by W. Rothfarb, N. P. Schein, and I. T. Frisch, which appeared as a letter to the editor in the January-February 1968 edition of Operations Research, describes an algorithm that solves a specific class of common terminal multi-commodity network flow problems. This note shows that this class of problems can also be formulated as single commodity minimal cost flow problems for which a number of solution techniques have been developed.
