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 heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend to survive and reproduce more than individuals with o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selection (genetic Algorithm)
Selection is the stage of a genetic algorithm in which individual genomes are chosen from a population for later breeding (using the crossover operator). A generic selection procedure may be implemented as follows: #The fitness function is evaluated for each individual, providing fitness values, which are then normalized. Normalization means dividing the fitness value of each individual by the sum of all fitness values, so that the sum of all resulting fitness values equals 1. #Accumulated normalized fitness values are computed: the accumulated fitness value of an individual is the sum of its own fitness value plus the fitness values of all the previous individuals; the accumulated fitness of the last individual should be 1, otherwise something went wrong in the normalization step. #A random number ''R'' between 0 and 1 is chosen. #The selected individual is the first one whose accumulated normalized value is greater than or equal to ''R''. For many problems the above algorithm m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adverse Selection
In economics, insurance, and risk management, adverse selection is a market situation where buyers and sellers have different information. The result is that participants with key information might participate selectively in trades at the expense of other parties who do not have the same information. In an ideal world, buyers should pay a price which reflects their willingness to pay and the value to them of the product or service, and sellers should sell at a price which reflects the quality of their goods and services. For example, a poor quality product should be inexpensive and a high quality product should have a high price. However, when one party holds information that the other party does not have, they have the opportunity to damage the other party by maximising self-utility, concealing relevant information, and perhaps even lying. Taking advantage of undisclosed information in an economic contract or trade of possession is known as adverse selection. This opportunity ...

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 writ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selektion
This is a list of words, terms, concepts and slogans of Nazi Germany used in the historiography covering the Nazi regime. Some words were coined by Adolf Hitler and other Nazi Party members. Other words and concepts were borrowed and appropriated, and other terms were already in use during the Weimar Republic. Finally, some are taken from Germany's cultural tradition. 0–9 * 25-point programme – The Nazi Party platform and a codification of its ideology.

Selection (Australian History)
Selection is the act of choosing and acquiring a subdivided tract of land for farming purposes in Australia. A selection is also descriptive of the plot of land that was selected. The term derived from "free selection before survey" of crown land in some Australian colonies under land legislation introduced in the 1860s. These acts were intended to encourage closer settlement, based on intensive agriculture, such as wheat-growing, rather than extensive agriculture, such as wool production. Selectors often came into conflict with squatters, who already occupied the land and often managed to circumvent the law. New South Wales The Robertson Land Acts allowed those with limited means to acquire land. With the stated intention of encouraging closer settlement and fairer allocation of land by allowing 'free selection before survey', the Land Acts legislation was passed in 1861. The relevant acts were named the ''Crown Lands Alienation Act'' and ''Crown Lands Occupation Act''. The a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preselection
Preselection is the process by which a candidate is selected, usually by a political party, to contest an election for political office. It is also referred to as candidate selection. It is a fundamental function of political parties. The preselection process may involve the party's executive or leader selecting a candidate or by some contested process. In countries that adopt Westminster-style responsible government, preselection is also the first step on the path to a position in the executive. The selected candidate is commonly referred to as the party's endorsed candidate. Deselection or disendorsement is the opposite procedure, when the political party withdraws its support from one of its elected office-holders. The party may then select a replacement candidate at the subsequent election, or it may decide (or be compelled by the electoral timetable) to forgo contesting that seat (for example, the Liberal Party of Australia after Pauline Hanson was disendorsed just before th ...

Selection Algorithm
In computer science, a selection algorithm is an algorithm for finding the ''k''th smallest number in a list or array; such a number is called the ''k''th ''order statistic''. This includes the cases of finding the minimum, maximum, and median elements. There are O(''n'')-time (worst-case linear time) selection algorithms, and sublinear performance is possible for structured data; in the extreme, O(1) for an array of sorted data. Selection is a subproblem of more complex problems like the nearest neighbor and shortest path problems. Many selection algorithms are derived by generalizing a sorting algorithm, and conversely some sorting algorithms can be derived as repeated application of selection. The simplest case of a selection algorithm is finding the minimum (or maximum) element by iterating through the list, keeping track of the running minimum – the minimum so far – (or maximum) and can be seen as related to the selection sort. Conversely, the hardest case of a selection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selection-based Search
A selection-based search system is a search engine system in which the user invokes a search query using only the mouse. A selection-based search system allows the user to search the internet for more information about any keyword or phrase contained within a document or webpage in any software application on their desktop computer using the mouse. Traditional browser-based search systems require the user to launch a web browser, navigate to a search page, type or paste a query into a search box, review a list of results, and click a hyperlink to view these results. Three characteristic features of a selection-based search system are that the user can invoke search using only their mouse from within the context of any application on their desktop (for example Microsoft Office, Adobe Reader, Mozilla Firefox, etc.), receive categorized suggestions which are based on the context of the user-selected text (or in some cases the wisdom of crowds), and view the results in floating infor ...
