Unconstrained Optimization

Release: 1.0

Date: Jan 05, 2025

Author: Jaroslav Fowkes, Nick Gould, Alexis Montoison and Dominique Orban

GALAHAD [1] is a suite of open-source routines for large-scale continuous optimization. Currently there are a pair of packages designed to find a local minimum of a function whose variables may take any values.

Contents

• ARC - unconstrained local optimization of a smooth function using a regularization method
• TRU - unconstrained local optimization of a smooth function using a trust-region method
