Cosmological Parameter Estimation with Genetic Algorithms [PDF]
Universe, 2023 Genetic algorithms are a powerful tool in optimization for single and multimodal functions. This paper provides an overview of their fundamentals with some analytical examples. In addition, we explore how they can be used as a parameter estimation tool in cosmological models to maximize the likelihood function, complementing the analysis with the ...

COMPARISON OF QUANTITATIVE GENETIC PARAMETERS [PDF]
Evolution, 1992 Shaw (1991) has described a maximum-likelihood procedure for comparing genetic covariance matrices between populations. While her efforts to expand the procedures available for quantitative genetic analyses are laudable, her discussion is incomplete in several respects. For example, consider her criticism of Dietz's matrix permutation test (Dietz, 1983)
