In this case the core of the algorithm is the primal iteration (S1) and the dual variable λ(t) is an internal state that determines the operating point.
In [20], Fazel et al. pointed out that the proximal matrix G should be as small as possible, while the subproblem related to the primal variable x is still relatively easy to tackle.
The problem reduces to finding a test space (a dimensionally reduced space for this auxiliary variable), which guarantees that the error in the primal variable (representing the solution) is close to the projection error of the full solution on the dimensionally reduced space that approximates the solution.
Most importantly, the primal variable at each iterate of the PDFP is feasible, but maybe not for that of the (mathrm{PDFP}^{2}mathrm{O}_{C}).
The dual variables will converge to the dual optimal as, and the primal variable will also converge to the primal optimal variable.

In the rest of this paper, the variable u is called primal variable and p is called dual variables [8].
If the dual variables were optimum, then the expressions for the primal variables would yield the optimum values.
