Difference in optimization options (OSLO, GENII etc.)

Question

Could you briefly explain the difference in your different optimization options(OSLO, GENII etc.)?

Synopsis

The difference in optimization options (OSLO, GENII etc.)

Solution

In order to perform an optimization in OSLO, you need to have an "Error Function" consisting of operands. The user can specify that OSLO creates default error functions by just specifying a few parameters.
  • The "GENII error function" allows the user to automatically create an aberration based error function - the implementation is derived from the old GENII optical design program. Available in all OSLO editions.
  • The "OLSO error function" allows the user to automatically create a ray-based error function. Available in OSLO Standard and Premium only.
See "Contents>>Optimization>>Error Functions>>Generate Error Functions" in the OSLO on-line help. Additionally, the OSLO Premium user can choose different "local" optimization engines: Downhill Simplex, Powell's Method, and Damped Least Squares (the OLSO default option - available in all editions of OSLO); as well as "global" optimization engines: Global Explorer and Adaptive Simulated Annealing (ASA). See "Contents>>Optimization>>Optimization Methods" in the OSLO on-line help. See chapter 8 in the OSLO 6.1 Optics Reference for a more detailed description of this entire subject area.
