Efficiency Enhancement of Genetic Algorithms via Building-Block-Wise Fitness Estimation [PDF]

open access: yes, 2004
This paper studies fitness inheritance as an efficiency enhancement technique for a class of competent genetic algorithms called estimation distribution algorithms. Probabilistic models of important sub-solutions are developed to estimate the fitness of a proportion of individuals in the population, thereby avoiding computationally expensive function ...

Epigenetics Algorithms: Self-Reinforcement-Attention mechanism to regulate chromosomes expression [PDF]

open access: yesarXiv, 2023
Genetic algorithms are a well-known example of bio-inspired heuristic methods. They mimic natural selection by modeling several operators such as mutation, crossover, and selection. Recent discoveries about Epigenetics regulation processes that occur "on top of" or "in addition to" the genetic basis for inheritance involve changes that affect and ...

Distributed Global Optimization (DGO) [PDF]

open access: yesProceedings of International Conference on Neural Networks (ICNN'96) June 1996, 2020
A new technique of global optimization and its applications in particular to neural networks are presented. The algorithm is also compared to other global optimization algorithms such as Gradient descent (GD), Monte Carlo (MC), Genetic Algorithm (GA) and other commercial packages.

Intelligent modelling of bioprocesses: A comparison of structured and unstructured approaches [PDF]

open access: yes, 2004
This contribution moves in the direction of answering some general questions about the most effective and useful ways of modelling bioprocesses. We investigate the characteristics of models that are good at extrapolating.

A Genetic Quantum Annealing Algorithm [PDF]

open access: yesarXiv, 2022
A genetic algorithm (GA) is a search-based optimization technique based on the principles of Genetics and Natural Selection. We present an algorithm which enhances the classical GA with input from quantum annealers. As in a classical GA, the algorithm works by breeding a population of possible solutions based on their fitness.

Evolutionary L∞ identification and model reduction for robust control [PDF]

open access: yes, 2000
An evolutionary approach for modern robust control oriented system identification and model reduction in the frequency domain is proposed. The technique provides both an optimized nominal model and a 'worst-case' additive or multiplicative uncertainty ...

Ancestral haplotype reconstruction in endogamous populations using identity-by-descent.

open access: yesPLoS Computational Biology, 2021
In this work we develop a novel algorithm for reconstructing the genomes of ancestral individuals, given genotype or sequence data from contemporary individuals and an extended pedigree of family relationships.

Kernel Density Estimation by Genetic Algorithm [PDF]

open access: yesarXiv, 2022
This study proposes a data condensation method for multivariate kernel density estimation by genetic algorithm. First, our proposed algorithm generates multiple subsamples of a given size with replacement from the original sample. The subsamples and their constituting data points are regarded as $\it{chromosome}$ and $\it{gene}$, respectively, in the ...

Evolving dynamic multiple-objective optimization problems with objective replacement [PDF]

open access: yes, 2005
This paper studies the strategies for multi-objective optimization in a dynamic environment. In particular, we focus on problems with objective replacement, where some objectives may be replaced with new objectives during evolution.

Systematic genetic analysis of the MHC region reveals mechanistic underpinnings of HLA type associations with disease. [PDF]

open access: yes, 2019
The MHC region is highly associated with autoimmune and infectious diseases. Here we conduct an in-depth interrogation of associations between genetic variation, gene expression and disease.
