Weak and Strong Superiorization: Between Feasibility-Seeking and Minimization
Yair Censor
We review the superiorization methodology, which can be thought of, in some cases, as lying between feasibility-seeking and constrained minimization. It is not quite trying to solv…
Projection Methods: An Annotated Bibliography of Books and Reviews
Yair Censor, Andrzej Cegielski
Projections onto sets are used in a wide variety of methods in optimization theory but not every method that uses projections really belongs to the class of projection methods as w…
Strict Fejér Monotonicity by Superiorization of Feasibility-Seeking Projection Methods
Yair Censor, Alexander J. Zaslavski
We consider the superiorization methodology, which can be thought of as lying between feasibility-seeking and constrained minimization. It is not quite trying to solve the full fle…
Zero-Convex Functions, Perturbation Resilience, and Subgradient Projections for Feasibility-Seeking Methods
Yair Censor, Daniel Reem
The convex feasibility problem (CFP) is at the core of the modeling of many problems in various areas of science. Subgradient projection methods are important tools for solving the…
String-Averaging Expectation-Maximization for Maximum Likelihood Estimation in Emission Tomography
E. S. Helou, Y. Censor, T. -B. Chen +4
We study the maximum likelihood model in emission tomography and propose a new family of algorithms for its solution, called String-Averaging Expectation-Maximization (SAEM). In th…
Performance of Hull-Detection Algorithms For Proton Computed Tomography Reconstruction
Blake Schultze, Micah Witt, Yair Censor +2
Proton computed tomography (pCT) is a novel imaging modality developed for patients receiving proton radiation therapy. The purpose of this work was to investigate hull-detection a…
Feasibility-Seeking and Superiorization Algorithms Applied to Inverse Treatment Planning in Radiation Therapy
R. Davidi, Y. Censor, R. W. Schulte +2
We apply the recently proposed superiorization methodology (SM) to the inverse planning problem in radiation therapy. The inverse planning problem is represented here as a constrai…
