This paper analyzes the behavior of the Nelderâ€“Mead simplex method for a family of examples which cause the method to converge to a nonstationary point. All the examples use continuous functions ofâ€¦ (More)

The revised simplex method is often the method of choice when solving large scale sparse linear programming problems, particularly when a family of closely-related problems is to be solved. Eachâ€¦ (More)

We present a new method of determining an operating policy for a multi-reservoir system in which the operating policy for a reservoir is determined by solving a stochastic dynamic programming modelâ€¦ (More)

In this paper, a flexible optimization-based framework for intentional islanding is presented. The decision is made of which transmission lines to switch in order to split the network whileâ€¦ (More)

A mathematical formulation for the islanding of power networks is presented. Given an area of uncertainty in the network, the proposed approach uses mixed integer linear programming to isolateâ€¦ (More)

Low pressure oil wells can be made to flow by the injection of gas into the well. The resulting flow from the well increases discontinuously with the amount of gas injected. A common way to modelâ€¦ (More)
