Using a Time Dependent Optimization problem as a benchmark we propose to improve the Genetic Algorithm’s adaptiveness by an appropriate diversity management dynamics. The so-called Dual Sharing GA is an extension of a former algorithm based on the use of a genotype to phenotype mapping. We experimentally evaluate the benefits over similar approaches to diversity management. We also analyze more...

Aquatic hyphomycete fungi are fundamental mediators of energy flow and nutrient spiraling in rivers. These microscopic fungi are primarily dispersed in river currents, undergo substantial annual fluctuations in abundance, and reproduce either predominantly or exclusively asexually. These aspects of aquatic hyphomycete biology are expected to influence levels and distributions of genetic diversi...

Aneuploidy is known to be deleterious and underlies several common human diseases, including cancer and genetic disorders such as trisomy 21 in Down's syndrome. In contrast, aneuploidy can also be advantageous and in fungi confers antifungal drug resistance and enables rapid adaptive evolution. We report here that sexual reproduction generates phenotypic and genotypic diversity in the human pat...
