An augmented Lagrangian algorithm for constrained nonlinear least-squares

Pierre Borie, Fabian Bastin, Stéphane Dellacherie

The paper proposes an algorithm that solves nonlinear least‑squares problems with mixed nonlinear and linear constraints by using an augmented Lagrangian formulation together with…
