Improving TSP Solutions Using GA with a New Hybrid Mutation Based on Knowledge and Randomness [PDF]

open access: yesarXiv, 2018
Genetic algorithm (GA) is an efficient tool for solving optimization problems by evolving solutions, as it mimics the Darwinian theory of natural evolution. The mutation operator is one of the key success factors in GA, as it is considered the exploration operator of GA.

Fixation of mutators in asexual populations: the role of genetic drift and epistasis [PDF]

open access: yesEvolution 67, 1143 (2013), 2012
We study the evolutionary dynamics of an asexual population of nonmutators and mutators on a class of epistatic fitness landscapes. We consider the situation in which all mutations are deleterious and mutators are produced from nonmutators continually at a constant rate.

Maximum likelihood (ML) estimators for scaled mutation parameters with a strand symmetric mutation model in equilibrium [PDF]

open access: yesarXiv, 2019
With the multiallelic parent-independent mutation-drift model, the equilibrium proportions of alleles are known to be Dirichlet distributed. A special case is the biallelic model, in which the proportions are beta distributed. A sample taken from these models is then Dirichlet-multinomially or beta-binomially distributed, respectively.

Clinical Diagnosis of X-Linked Spondyloepiphyseal Dysplasia Tarda and a Novel Missense Mutation in the Sedlin Gene (SEDL)

open access: yesInternational Journal of Endocrinology, 2018
Objective. Spondyloepiphyseal dysplasia tarda (SEDT) is a rare hereditary bone disease characterized by spinal and epiphyseal anomalies. We identified the disease by gene sequencing in a Chinese pedigree with SEDT. Methods.

The age incidence of any cancer can be explained by a one-mutation model [PDF]

open access: yesarXiv, 2008
We propose a one mutation model for cancer with a mutation rate that increases with time. Under rather general hypotheses the number of mutations is necessarily a (non homogeneous) Poisson process with the prescribed mutation rate. We show that the cumulative probability of cancer up to time $t$ is, up to a multiplicative constant, an antiderivative of
