Can Linear Superiorization Be Useful for Linear Optimization Problems? [PDF]
, 2016 Linear superiorization considers linear programming problems but instead of attempting to solve them with linear optimization methods it employs perturbation resilient feasibility-seeking algorithms and steers them toward reduced (not necessarily minimal) target function values.

Superiorization of Incremental Optimization Algorithms for Statistical Tomographic Image Reconstruction [PDF]
, 2016 We propose the superiorization of incremental algorithms for tomographic image reconstruction. The resulting methods follow a better path in its way to finding the optimal solution for the maximum likelihood problem in the sense that they are closer to the Pareto optimal curve than the non-superiorized techniques.

Structural pattern of the Todos Santos Coastal Plain, based on geophysical data
Ciencias Marinas, 2004 A set of gravity and magnetic data taken within the Todos Santos Coastal Plain between 1962 and 2000 from land, sea and air is used to integrate the structural framework and tectonic model of this area. The present work collected all the available data,

A Direct Approach to Simultaneous Tests of Superiority and Noninferiority with Multiple Endpoints [PDF]
arXiv, 2023 Simultaneous tests of superiority and non-inferiority hypotheses on multiple endpoints are often performed in clinical trials to demonstrate that a new treatment is superior over a control on at least one endpoint and non-inferior on the remaining endpoints.

Yucatan Current variability through the Cozumel and Yucatan channels
Ciencias Marinas, 2011 A comparison based on eight months of simultaneous observations of the flow variability in the Yucatan and Cozumel channels shows that the portion of the Yucatan Current that crosses through Cozumel Channel is best correlated with the flow near the ...

Superiorization as a novel strategy for linearly constrained inverse radiotherapy treatment planning [PDF]
arXiv, 2022 We apply the superiorization methodology to the intensity-modulated radiation therapy (IMRT) treatment planning problem. In superiorization, linear voxel dose inequality constraints are the fundamental modeling tool within which a feasibility-seeking projection algorithm will seek a feasible point. This algorithm is then perturbed with gradient descent
