- Abstract
- The field of constrained non-linear optimization is one of the most practically applicable areas of mathematics. It has been used successfully to solve problems in a wide range of areas including economics, communications and computational chemistry. In recent years some problem reformulation techniques have been suggested for dealing with non-convex problems. However most of this study has been of a theoretical nature and very little is known about its effect on the practical impact of these techniques. In this seminar we will outline some of the reformulation techniques which have been suggested and present numerical results which show their relative efficiencies in solving some test problems. We will ultimately suggest that a reformulation scheme which combines a logarithmic reformulation of the objective function and an exponential reformulation of the constraint function provides many desirable outcomes.; E1
