Paper Abstract

Damped Least Squares (DLS) optimization techniques have been used in lens design programs for many years. Although capable of significant improvement in a wide range of applications DLS techniques often converge to local merit function minima. Generalized Simulated Annealing (GSA) algorithms have been suggested as an alternative to DLS in order to arrive at a global merit function minima, and to reduce the dependance on operator expertise. In this paper we describe an effort to use the preliminary results of the DLS process to provide a starting point in a semi automatic manner for the GSA algorithm.
