Uno: R Interface to the 'Uno' Nonlinear Optimization Solver
Bindings to 'Uno' (Unifying Nonlinear Optimization), a C++ solver
for smooth nonlinearly constrained optimization. 'Uno' unifies Lagrange-Newton
methods, including sequential quadratic programming and interior-point
methods, by decomposing them into interacting building blocks
(constraint-relaxation, inequality-handling, Hessian, and globalization
strategies) that can be freely combined, either through options or through
presets that reproduce established solvers such as 'filterSQP' and 'IPOPT'.
The framework is described in Vanaret and Leyffer (2024)
<doi:10.48550/arXiv.2406.13454>.
