This method also produces a sorted version of the collection, which may be useful for other later computations, and in particular for selection with other choices of . [ 3 ] For a sorting algorithm that generates one item at a time, such as selection sort , the scan can be done in tandem with the sort, and the sort can be terminated once the k ...
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 (e.g. a heuristic).
In computer programming, the strategy pattern (also known as the policy pattern) is a behavioral software design pattern that enables selecting an algorithm at runtime. Instead of implementing a single algorithm directly, code receives runtime instructions as to which in a family of algorithms to use.
It is also believed BAs could be successfully applied to complex positioning problems (antennas for cell phones, urban planning, and so on) or data mining. [66] Cultural algorithm (CA) consists of the population component almost identical to that of the genetic algorithm and, in addition, a knowledge component called the belief space.
For valid arguments, the logical structure of the premises and the conclusion follows a pattern called a rule of inference. [12] For example, modus ponens is a rule of inference according to which all arguments of the form "(1) p , (2) if p then q , (3) therefore q " are valid, independent of what the terms p and q stand for.

That would be an example of regular natural selection – a phenomenon called "the selfish herd". Systematics is the branch of biology that attempts to establish patterns of relationship among biological taxa, today generally thought to reflect evolutionary history. It is also concerned with their classification.
The set of all solutions, also called individuals according to the biological model, is known as the population. [ 1 ] [ 2 ] The genome of an individual consists of one, more rarely of several, [ 3 ] [ 4 ] chromosomes and corresponds to the genetic representation of the task to be solved.
A choice function (also called selector or selection) is a function f, defined on a collection X of nonempty sets, such that for every set A in X, f(A) is an element of A. With this concept, the axiom can be stated:
