  • evolutionary algorithm — (EA) An algorithm which incorporates aspects of natural selection or survival of the fittest. An evolutionary algorithm maintains a population of structures (usually randomly generated initially), that evolves according to rules of selection, recombination, mutation and survival, referred to as genetic operators. A shared "environment" determines the fitness or performance of each individual in the population. The fittest individuals are more likely to be selected for reproduction (retention or duplication), while recombination and mutation modify those individuals, yielding potentially superior ones. EAs are one kind of evolutionary computation and differ from genetic algorithms. A GA generates each individual from some encoded form known as a "chromosome" and it is these which are combined or mutated to breed new individuals. EAs are useful for optimisation when other techniques such as gradient descent or direct, analytical discovery are not possible. Combinatoric and real-valued function optimisation in which the optimisation surface or fitness landscape is "rugged", possessing many locally optimal solutions, are well suited for evolutionary algorithms.
  • extra-mural department — a university department that offers courses for part-time students
  • flushed with something — very excited because of some success or triumph
  • friar minor conventual — a friar belonging to a branch of the Franciscan order that separated from the Observants in the 15th century, and that observes a modification of the rule of St. Francis. Also called Conventual. Compare Friar Minor, capuchin (def 4).
  • functional programming — (programming)   (FP) A program in a functional language consists of a set of (possibly recursive) function definitions and an expression whose value is output as the program's result. Functional languages are one kind of declarative language. They are mostly based on the typed lambda-calculus with constants. There are no side-effects to expression evaluation so an expression, e.g. a function applied to certain arguments, will always evaluate to the same value (if its evaluation terminates). Furthermore, an expression can always be replaced by its value without changing the overall result (referential transparency). The order of evaluation of subexpressions is determined by the language's evaluation strategy. In a strict (call-by-value) language this will specify that arguments are evaluated before applying a function whereas in a non-strict (call-by-name) language arguments are passed unevaluated. Programs written in a functional language are generally compact and elegant, but have tended, until recently, to run slowly and require a lot of memory. Examples of purely functional languages are Clean, FP, Haskell, Hope, Joy, LML, Miranda, and SML. Many other languages such as Lisp have a subset which is purely functional but also contain non-functional constructs. See also lazy evaluation, reduction.

  • mcculloch-pitts neuron — (artificial intelligence)   The basic building block of artificial neural networks. It receives one or more inputs and produces one or more identical outputs, each of which is a simple non-linear function of the sum of the inputs to the neuron. The non-linear function is typically a threshhold or step function which is usually smoothed (i.e. a sigmoid) to facilitate learning.

  • nominal semidestructor — (abuse)   Slang for "National Semiconductor", found among other places in the 4.3BSD networking sources. During the late 1970s to mid-1980s this company marketed a series of microprocessors including the National Semiconductor 16000 and National Semiconductor 32000. At one point early in the great microprocessor race, the specs on these chips made them look like serious competition for the rising Intel 80x86 and Motorola 680x0 series. Unfortunately, the actual parts were notoriously flaky and never implemented the full instruction set promised in their literature, apparently because the company couldn't get any of the mask steppings to work as designed. They eventually sank without trace, joining the Zilog Z8000 and a few even more obscure also-rans in the graveyard of forgotten microprocessors.
  • non-euclidean geometry — geometry based upon one or more postulates that differ from those of Euclid, especially from the postulate that only one line may be drawn through a given point parallel to a given line.
  • non-maskable interrupt — (NMI) An IRQ 7 on the PDP-11 or 680x0 or the NMI line on an 80x86. In contrast with a priority interrupt (which might be ignored, although that is unlikely), an NMI is *never* ignored.
  • normal order reduction — Under this evaluation strategy an expression is evaluated by reducing the leftmost outermost redex first. This method will terminate for any expression for which termination is possible, whereas applicative order reduction may not. This method is equivalent to passing arguments unevaluated because arguments are initially to the right of functions applied to them. See also computational adequacy theorem.
