WebbProximal point algorithm, on the other hand, solves optimization with D h constraints iteratively, until an optimal solution is reached. Exact proximal point method is when (6) solved exactly. It provides a feasible solution that is closest to the optimal solution set in each step, and finally reach an optimal solution. Inexact proximal point ...
