K-Bit-Swap: A New Operator For Real-Coded Evolutionary Algorithms

no code implementations22 Apr 2016 Aram Ter-Sarkisov, Stephen Marsland

There has been a variety of crossover operators proposed for Real-Coded Genetic Algorithms (RCGAs), which recombine values from the same location in pairs of strings.

Möbius Invariants of Shapes and Images

no code implementations30 Mar 2016 Stephen Marsland, Robert McLachlan

In this paper we study the invariants of planar shapes and images under the M\"obius group $\mathrm{PSL}(2,\mathbb{C})$, which arises in the conformal camera model of vision and may also correspond to neurological aspects of vision, such as grouping of lines and circles.

Principal Autoparallel Analysis: Data Analysis in Weitzenböck Space

no code implementations11 Nov 2015 Stephen Marsland, Carole J. Twining

In this paper we transfer the problem to Weitzenb\"{o}ck space, which has torsion, but not curvature, meaning that parallel transport is path independent, and rather than considering geodesics, it is natural to consider autoparallels, which are `straight' in the sense that they follow the local basis vectors.

Derivation of Upper Bounds on Optimization Time of Population-Based Evolutionary Algorithm on a Function with Fitness Plateaus Using Elitism Levels Traverse Mechanism

no code implementations11 Apr 2012 Aram Ter-Sarkisov, Stephen Marsland

In this article a tool for the analysis of population-based EAs is used to derive asymptotic upper bounds on the optimization time of the algorithm solving Royal Roads problem, a test function with plateaus of fitness.
