Abstract

In this paper we investigate the generalized Gauss–Newton method in the following form

x n+1 = ξn θ(F′*(xn )F′(xn ), τn )F′*(xn ){(F(xn ) – ƒδ) – F′(xn )(xn ξn )}, x 0, ξn ∈ 𝒟 ⊂ H 1.

The modified source condition

which depends on the current iteration point xn , is used. We call this inclusion the undetermined reverse connection. The new source condition leads to a much larger set of admissible control elements ξn as compared to the previously studied versions, where ξn = ξ. The process is combined with a novel a posteriori stopping rule, where is the number of the first transition of ‖F(xn ) – ƒδ‖ through the given level δω , 0, < ω < 1, i.e.,

The convergence analysis of the proposed algorithm is given.

Keywords.: Stopping rule; discrepancy principle; ill-posed problem; iterative regularization; Fréchet derivative; Gauss–Newton's method
