Algorithm 2

Set to an initial guess;
, Compute and at with Algorithm 1;
Perform wavelet transform for and level by level to
obtain and for , with and
being the wavelet transform at the th level
for and ;
(4) Set and ;
While
Obtain a solution from using the CGD
method with an initial value ;
Prolongate through padding zeros to obtain an initial
guess for at the next higher resolution, that is,
