A variational approach to optimal two‐stage designs

Statistics in Medicine, 2019
Recalculating the sample size in adaptive two‐stage designs is a well‐established method to gain flexibility in a clinical trial. Jennison and Turnbull (2015) proposed an “optimal” adaptive two‐stage design based on the inverse normal combination test, which minimizes a mixed criterion of expected sample size under the alternative and conditional power.

Optimization of Aortic Arch Replacement: Two-Stage Approach

The Annals of Thoracic Surgery, 2007
Aneurysms of the aortic arch seldom occur alone. They usually involve the ascending aorta. Occasionally, the aneurysm also involves the descending thoracic or thoracoabdominal aorta. We advocate a staged approach for repair of these extensive aortic aneurysms, with the ascending and arch generally being repaired in the first stage and the descending ...

A two-stage coevolution approach for constrained optimization

Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2017
In this paper, a coevolution approach with two stages is proposed for constrained optimization problems (COPs). At the first stage, the approach enters the feasible region rapidly by utilizing the feasibility rule with incorporation of objective function information (FROFI), which is an effective method for the balance between constraints and objective
