The GENITOR Algorithm and Selection Pressure: Why Rank-Based Allocation of Reproductive Trials is Best
- Proceedings of the Third International Conference on Genetic Algorithms
, 1989
"... This paper reports work done over the past three years using rank-based allocation of reproductive trials. New evidence and arguments are presented which suggest that allocating reproductive trials according to rank is superior to fitness proportionate reproduction. Ranking can not only be used to s ..."

to slow search speed, but also to increase search speed when appropriate. Furthermore, the use of ranking provides a degree of control over selective pressure that is not possible with fitness proportionate reproduction. The use of rank-based allocation of reproductive trials is discussed in the context
Tuning Selection Pressure in Tournament Selection
"... Selection pressure controls the selection of individuals from the current population to produce a new population in the next generation. It gives individuals of higher quality a higher probability of being used to create the next generation so that Evolutionary Algorithms (EAs) can focus on promisin ..."

Selective pressures on genomes in molecular evolution.
- Journal of Theoretical Biology,
, 2003
"... Abstract We describe the evolution of macromolecules as an information transmission process and apply tools from Shannon information theory to it. This allows us to isolate three independent, competing selective pressures that we term compression, transmission, and neutrality selection. The first t ..."

Selection Pressure in Alternative Reading Frames
"... Overlapping genes are two protein-coding sequences sharing a significant part of the same DNA locus in different reading frames. Although in recent times an increasing number of examples have been found in bacteria the underlying mechanisms of their evolution are unknown. In this work we explore how ..."

how selective pressure in a protein-coding sequence influences its overlapping genes in alternative reading frames. We model evolution using a time-continuous Markov process and derive the corresponding model for the remaining frames to quantify selection pressure and genetic noise. Our findings lead
On the influence of lifetime learning on selection pressure
- in ‘Artificial Life 10
, 2006
"... Evidence for both, acceleration and deceleration of evolution through learning can be found in the literature. We suggest a selection gradient model that allows to predict whether acceleration or deceleration is predominant. The main idea is that learning alters the genotype-to-fitness landscape, wh ..."

, which determines selection pressure. Assuming that fitness can be split up into an innate and a learned component, conditions for the occurrence of the Baldwin and the Hiding effect are derived. We introduce learning curves to analyse what we term lifetime fitness. The influence of the shape
Selective pressure in evolutionary algorithms: A characterization of selection mechanisms
- Proceedings of the First IEEE Conference on Evolutionary Computation
, 1994
"... baeck0lsll.informatik.uni-dortmund.de Abstract-Due to its independenceof the actual search space and its impact on the exploration-exploitation tradeoff, selection is an important operator in any kind of Evolutionary Algorithm. In this paper, all important selection op erators are discussed and quan ..."

and quantitatively compared with respect to their selective pressure. The comparison clarifies that only a few really different and useful selection operators exist: Proportional selection (in combination with a scaling method), linear ranking, tournament selection, and (?,A)-selection (respectively (p+A)-selection
Selection Pressure and Performance in Spatially Distributed Evolutionary
- In Proceedings of the World Congress on Computatinal Intelligence
, 1998
"... Recent studies of spatially distributed EAs have formally characterized the selection pressure induced by various selection strategies applied to local neighborhoods of various sizes and shapes. These analyses provide us with the ability to predict the expected behavior of the local neighborhood EAs ..."

The resistance ratchet: theoretical implications of cyclic selection pressure
- J. of Antimicrobial Chemotherapy

Methods: The model assumed that resistance in microbial ecologies changes slowly with changing selection pressure, at a rate proportional to the difference between the curren ..."

Modeling Selection Pressure in XCS for Proportionate and Tournament Selection

We show that these models can explain the empirical results that have been previously presented in the literature. We validate the models on simple problems showing ..."
