A customized proximal point algorithm for convex minimization with linear constraints

He, Bingsheng; Yuan, Xiaoming; Zhang, Wenxing - In: Computational Optimization and Applications 56 (2013) 3, pp. 559-572

This paper demonstrates a customized application of the classical proximal point algorithm (PPA) to the convex … minimization problem with linear constraints. We show that if the proximal parameter in metric form is chosen appropriately, the …

An extension of the proximal point algorithm with Bregman distances on Hadamard manifolds

Quiroz, E. Papa - In: Journal of Global Optimization 56 (2013) 1, pp. 43-59

In this paper we present an extension of the proximal point algorithm with Bregman distances to solve constrained minimization problems with quasiconvex and convex objective function on Hadamard manifolds. The proposed algorithm is a modified and extended version of the one presented in Papa...
