Optimal Control of a Nonlinear Elliptic Problem With Missing Data

---

Résumé

In this work, we give a characterization of the control for ill-posed problems. We propose the regularization method
which consists in improving the data in order to obtain a well-posed problems. As the problem is nonlinear, we will use
the adapted low-regret control method in order to be able to respectively determine the charaterization of the low-regret
and no-regret control of the problem
