The NRB Algorithm is derived by extending the Surrogate Worth Trade‐Off method to quadratic programming. This category of problem is common in water resources planning and design, especially multipurpose reservoir systems. Consequently, an example is given using the algorithm for optimally operating a multipurpose reservoir. Copyright © 1988, Wiley Blackwell.
