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 ... WebbKiwiel, K.

Asymptotic Convergence Analysis of the Proximal Point Algorithm
Webb15 feb. 2024 · Abstract. In this paper, we introduce a proximal point algorithm for approximating a common solution of finite family of convex minimization problems and fixed point problems for -demicontractive mappings in complete CAT(0) spaces. We prove a strong convergence result and obtain other consequence results which generalize and … WebbThe asymptotic convergence of the proximal point algorithm (PPA), for the solution of equations of type 0 ∈ T z, where T is a multivalued maximal monotone operator in a real … WebbProximal point algorithms are useful for optimisation in machine learning and statistics for obtaining solutions with composite objective functions.
