Global Optimization: A Tool for Successful Design

Facebook X LinkedIn Email
Optical Research Associates’ Global Synthesis (GS) algorithm has been in use for more than ten years. During that time, the algorithm has been applied to numerous types of problems, and has proved remarkably successful with an approach that is feasible for both large (e.g., >90 variables) and small problems running on personal computers.

Thomas G. Kuper and Thomas I. Harris, Optical Research Associates

Some efforts in global optimization research for optical design center around probabilistic methods such as global search. While promising for small problems with few variables, these methods approach being exponential in the number of variables (N), and the time required to find a solution is: where f is the number of function evaluations for each variable. The high rate of time scale-up with the number of variables has led to research into algorithmic ways to mitigate the scale-up (such as simulated annealing and genetic algorithms), to the consideration of specialized...Read full article
