trust_project_scaled

<p>Projects candidate onto trust region with coordinate-wise
metric scaling</p>

internal

Implements the GALAHAD algorithm (Geometry-Adaptive
'Lyapunov'-Assured Hybrid Optimizer), combining 'Riemannian' metrics,
'Lyapunov' stability checks, and trust-region methods for stable
optimization of mixed-geometry parameters. Designed for biological
modeling (germination, dose-response, survival) where rates,
concentrations, and unconstrained variables coexist. Developed at
the Minnesota Center for Prion Research and Outreach (MNPRO),
University of Minnesota. Based on Conn et al. (2000)
