NETGEN, a program for generating network problems has been described in recent issues of the Journal of Management Science and the SIGMAP Newsletter. NETGEN's authors, Messrs. D. Klingman A. Napier and J. Stutz, described NETGEN as a general purpose code for "generating a variety of feasible network problems . . . capacitated and uncapacitated transportation and minimum cost flow network problems". Furthermore, say the authors, "researchers can generate identical networks using this code. . .". While this description would seem to reveal a potentially valuable tool for scientists working in the field of network problems, this researcher has encountered several difficulties in utilizing the NETGEN program.
