Augmented Lagrangian methods for convex optimization with priority constraints via an infeasibility control framework

Yuya Yamakawa, Shota Yamanaka, Nobuo Yamashita

We consider convex optimization problems with prioritized equality constraints, which may be infeasible. In many applications, such as network optimization and image reconstruction…
