Improved Squeaky Wheel Optimisation for Driver Scheduling, Uwe Aickelin, Edmund K. Burke, Jingpeng Li • SWO is an algorithm based on a construction-analysis-prioritization cycle. • Improved ISWO introduces selection and mutation within the solution. • Each component must prove its fitness. • Driver scheduling involves partitioning blocks of work (1 vehicle each) into legal shifts • set covering integer linear programming problem.
Search bias in ant colony optimization: on the role of competition-balanced systems Blum, C.; Dorigo, M.
An Evolutionary Approach to the Inference ofPhylogenetic Networks,Juan Diego Trujillo and Carlos Cotta • Trying to find a phylogenetic network that models a set of sequences of molecular data using EAs • Networks include reticulation events (horizontal transfer, recombination, hybridization). • Heuristics based genetic operators. • Fitness function based on likelihood. • Network models close to evolutionary model hidden in the data.

Genetic Algorithm based on Independent ComponentAnalysis for Global OptimizationGang Li, Kin Hong Lee, Kwong Sak Leung • ICA projects an n-dimensional set to a lower-dimensional space. • Since components are independent of each other, they can be independently maximized. • Solutions are comparable to other algorithms, but fewer fitness evaluations.
When Do Heavy-Tail Distributions Help?Hansen, Gemperle, Auger, and Koumoutsakos • Cauchy distribution is an example of heavy-tail. • As opposed to gaussian. • Studies the probability of sampling a better solution using different Cauchy distribution. • Anisotropic Cauchy obtains exceptionally good results on Rastrigin function.

Neuroevolution with Analog Genetic EncodingPeter Dürr, Claudio Mattiussi, and Dario Floreano • Recent paper by Banzhaf et al. In Nature Reviews-Genetics request following more closely known biological facts in EC to convert it into computational evolution. • This paper uses an encoding for neural nets closer to real genomes • Based on tokens that represent problem objects. • With operators to match

Assortative mating drastically alters themagnitude of error thresholdsGabriela Ochoa and Klaus Jaffe • Beyond the error threshold, evolved structures cannot be reproduced in the quasispecies evolution model (Eigen and Schuster). • In EC, related to the exploration/exploitation balance. • Assortative mating produces the highest error threshold, whereas asexual reproduction produces the lowest.

Self-regulated Population Size inEvolutionary AlgorithmsCarlos Fernandes and Agostinho Rosa • There are many self-regulated population algorithms: GAVaPS, APGA, ProFiGa: • Funky acronym not a requisite. • Some based on age. • SRP-EA combines CHC and GAVaPS. • Achieves better success rates, with a penalty in the number of evaluations.
Is Self-Adaptation of Selection Pressure andPopulation Size Possible? – a Case StudyA.E. Eiben M.C. Schut A.R. de Wilde • Self-adapting selection operators and population size can yield as good or better results than self-adapting operators. • Selection parameters are encoded in individuals, and a consensus value is reached. • Self-adapting selection increases speed.
