Projected Subgradient Minimization versus Superiorization
Yair Censor, Ran Davidi, Gabor T. Herman +2
The projected subgradient method for constrained minimization repeatedly interlaces subgradient steps for the objective function with projections onto the feasible region, which is…
Superiorization: An optimization heuristic for medical physics
G. T. Herman, E. Garduño, R. Davidi +1
Purpose: To describe and mathematically validate the superiorization methodology, which is a recently-developed heuristic approach to optimization, and to discuss its applicability…
Perturbation Resilience and Superiorization of Iterative Algorithms
Y. Censor, R. Davidi, G. T. Herman
Iterative algorithms aimed at solving some problems are discussed. For certain problems, such as finding a common point in the intersection of a finite number of convex sets, there…
On the Effectiveness of Projection Methods for Convex Feasibility Problems with Linear Inequality Constraints
Y. Censor, W. Chen, P. L. Combettes +2
The effectiveness of projection methods for solving systems of linear inequalities is investigated. It is shown that they have a computational advantage over some alternatives and…
