The problem is characterized as ill-posed, meaning that the solution (if it exists) does not depend continuously on the measur able data. To address the inherent instability of this problem, we introduce two regularization strategies: the first employs a modified quasi-boundary value method, and the second utilizes a variant of the quasi-reversibility technique. We present convergence results under an a priori bound assumption and propose a practical a posteriori parameter selection rule.enArticle
