FRED Optimum includes a general multi-parameter optimization feature designed to address a wide range of applications. Performance criteria are specified through user-defined or built-in merit functions and applied with Simplex (multi-variable) or 1-D (single variable) methods.
Why is FRED Optimum’s hybrid optimization different than lens design optimization? FRED’s new hybrid general optimization algorithm is non-sequential, allows for multiple targets, has fractional weighting capability to link variables and utilizes several built-in merit functions plus a user-defined scripted merit function for unusual tasks.
The hybrid algorithm has the full capability to optimize surfaces created directly in FRED as shown in the figure below or imported from CAD as NURBS. This optimization scheme gives the user complete control over variables, merit functions and optimization algorithms to solve the toughest illumination design problems.
FRED Optimum’s menus are easy to use: tabbed, built-in spreadsheets that define the variables, the merit functions, and the optimization methods.
The unique hybrid optimization algorithms in FRED allow the user to select multiple target surfaces with different weights during optimization. This multiple target functionality creates a multitude of scenarios where the user can optimize on different targets using different criteria.
