    Source: IEEE Transactions on Evolutionary Computation
    DOI: 10.1109/TEVC.2017.2712906

Bilevel optimization is defined as a mathematical program, where an optimization problem contains another optimization problem as a constraint. These problems have received significant attention from the mathematical programming community. Only limited work exists on bilevel problems using evolution...(Read Full Abstract)

A statistical model for helices with applications

  • Authors: Mardia K.V., Sriram K., Deane C.M.

    DOI: 10.1111/biom.12870

Motivated by a cutting edge problem related to the shape of ?-helices in proteins, we formulate a parametric statistical model, which incorporates the cylindrical nature of the helix. Our focus is to detect a "kink," which is a drastic change in the axial direction of the helix. We propose a statist...(Read Full Abstract)

Voting Advice Applications (VAAs) are online decision support systems that try to match voters with political parties or candidates in elections, typically based on how each responds to a number of policy issue statements. Such VAAs play a major role in many countries. In this paper, we describe the...(Read Full Abstract)
