Selection (biology)
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the Heredity, heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which is intentional, whereas natural selection is not. Genetic diversity, Variation of traits, both Genotype, genotypic and phenotypic, exists within all populations of organisms. However, some traits are more likely to facilitate survival and reproductive success. Thus, these traits are passed the next generation. These traits can also become more Allele frequency, common within a population if the environment that favours these traits remains fixed. If new traits become more favoured due to changes in a specific Ecological niche, niche, microevolution occurs. If new traits become more favoured due to changes in the ...

Selection (evolutionary Algorithm)
Selection is a genetic operator in an evolutionary algorithm (EA). An EA is a metaheuristic inspired by biological evolution and aims to solve challenging problems at least approximately. Selection has a dual purpose: on the one hand, it can choose individual genomes from a population for subsequent breeding (e.g., using the crossover operator). In addition, selection mechanisms are also used to choose candidate solutions (individuals) for the next generation. The biological model is natural selection. Retaining the best individual(s) of one generation unchanged in the next generation is called ''elitism'' or ''elitist selection''. It is a successful (slight) variant of the general process of constructing a new population. The basis for selection is the quality of an individual, which is determined by the fitness function. In memetic algorithms, an extension of EA, selection also takes place in the selection of those offspring that are to be improved with the help of a meme ( ...

The Selection
''The Selection'' is a young adult novel by Kiera Cass first published on April 14, 2012, by HarperCollins. It is the first in a five-book series, followed by '' The Elite'' (2013), ''The One'' (2014), ''The Heir'' (2015) and ''The Crown'' (May 2016). The last two take place twenty years after the events in the first three. In addition, four spin-off novellas were released. The first two, ''The Prince'' and ''The Guard'', are narrated from the point of view of two supporting characters. ''The Queen'' and ''The Favorite'' are prequels, focusing on two other supporting characters in the main series. All four novellas were collected into one volume ''Happily Ever After'', including bonus content and epilogues. Kiera Cass stated that she began writing ''The Selection'' after thinking about the differences between Esther and Cinderella, wondering if either of them were happy with how they ended up. She also commented that she had written the book "from start to finish", while her wr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selection (Nazi Concentration Camps)
"Selection" (German language, German: ') is the name given to the process of designating inmates either for murder or Forced labour under German rule during World War II, forced labor at a Nazi concentration camps, Nazi concentration camp. The arrival selection was first a separation by sex, and then a separation into either fit or unfit for work, as determined by a soldier, bureaucrat or doctor after a visual inspection or perhaps a question or two. Children under 16 (later 14), the elderly, women visibly pregnant, mothers who would not leave their children, the disabled, or anyone visibly weak or ill, were ineligible for "selection" and were immediately murdered. In addition to the initial selection upon arrival, subsequent selections would occur at subsequent prisoner counts, the , or in the , the camp barracks. The selection officers were nominally looking for healthier, stronger laborers, but according to historian Jan Erik Schulte, camp guards and administrators were given ...
