Regularized solution of a nonlinear discrete inverse problem

A numerical scheme for the regularized conjugate gradient method 

The critical point of regularization methods is the definition of tlic regularization paraiiK U r o. As w( discuss( d in Cha])ter 4, for the solution of this problem it is 

One c ui tilso use m adaptivt regularization in the sense discussed in (, hapter 1. In this case flit regularization paraincter a is updated on each iteration. The basic ideas of tht atlaptive mt thod will be discussed in section 5.3.
