Optimization

This section covers the optimization functionality of the Optiland package. The optimization module provides a set of tools for optimizing optical systems. It includes a variety of optimization algorithms, such as gradient-based and evolutionary algorithms, as well as tools for defining optimization variables and objectives.

For thin film and coating specific optimization (e.g., Needle Synthesis), see the Thin Film module.

The optimization module is divided into four subcategories:

Core Functionalities - Problem definition and optimizers
Operands - Functions to compute optical performance metrics
Variables - Properties of optical elements that can be optimized
Scaling - Methods to scale optimization variables for better performance
