MRS. KIRBY joined Bell Telephone Laboratories in 1952 after graduating from the University of Vermont where she majored in mathematics. She received an MS in mathematics from NYU in 1961 and has taken additional courses at Stevens Institute of Technology.Mrs. Kirby is a member of the company's Transmission Network and Analysis Department and has programmed for a wide variety of digital computers. She first engaged in mathematical work in connection with network design and authored several general purpose programs for the analysis of electrical circuits. More recently she has been using digital computers as a tool in the design and analysis of various communication systems. This has included programs to produce wiring diagrams, the simulation of a high speed digital transmission system repeatered link in order to specify equalization, and a program to produce statistics on the fading of radio signals. She is currently working on a monitor system for a small real-time digital computer. ABSTRACT A general-purpose optimization program, using the methods of steepest descent and multidimensional NewtonRaphson, has been developed for the IBM 7094. The program can be used independently or as part of a manmachine optimization system in which the engineer can quickly appraise the effect of changes in problem parameters. Man-machine interaction at a remote location is provided through an experimental console which consists of a Packard-Bell PB-250 computer and associated input-output equipment.The program and equipment configuration used for interaction will be described and an example of network optimization using this system will be presented.An optimization scheme which is designed for a digital computer offers a more sophisticated strategy and better accuracy than a scheme designed for an analog computer. The current interaction system is of limited form; nevertheless, work done with it has aided in defining the objectives for a more flexible man-digital machine interaction system.
