ROL aims to combine flexibility, efficiency and robustness. Key features:
- Matrix-free application programming interfaces (APIs) —enable direct use of application data structures and memory spaces, linear solvers, nonlinear solvers and preconditioners.
- State-of-the-art algorithms for unconstrained optimization, constrained optimization and optimization under uncertainty —enable inexact and adaptive function evaluations and iterative linear system solves.
- Special APIs for simulation-based optimization —enable a streamlined embedding into engineering applications, rigorous implementation verification and efficient use.
- Modular interfaces throughout the optimization process —enable custom and user-defined algorithms, stopping criteria, hierarchies of algorithms, and selective use of a variety of tools and components.
