We are presenting a modification of the well-known Alternating DirectionMethod of Multipliers (ADMM) algorithm with additional preconditioning thataims at solving convex optimisation problems with nonlinear operatorconstraints. Connections to the recently developed Nonlinear Primal-Dual HybridGradient Method (NL-PDHGM) are presented, and the algorithm is demonstrated tohandle the nonlinear inverse problem of parallel Magnetic Resonance Imaging(MRI).
