George, S.Padikkal, J.Remesh, K.Argyros, I.K.2026-02-042022Mathematics, 2022, 10, 18, pp. -https://doi.org/10.3390/math10183365https://idr.nitk.ac.in/handle/123456789/22415In this paper, we introduced a new source condition and a new parameter-choice strategy which also gives the known best error estimate. To obtain the results we used the assumptions used in earlier studies. Further, we studied the proposed new parameter-choice strategy and applied it to the method (in the finite-dimensional setting) considered in George and Nair (2017). © 2022 by the authors.a new parameter-choice strategyfinite dimensioniterative methodLavrentiev regularizationnonlinear ill-posed equations
