An Algorithm for Globally-Optimal Nonlinear-Cost Multidimensional Flows in Networks and Some Special Applications.

This paper describes an algorithm that finds globally optimum flows in networks having nonlinear costs of arc flows, the flows being finite-dimensional vectors such as multicommodity flows. The algorithm is an extension of an idea of ALLSOP [Trans. Sci. 2, 1–13 (1968)] for minimizing total delays in a traffic network; it is also intimately related to results in nonserial dynamic programming. [ABSTRACT FROM AUTHOR]
