Description: 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)
