  • evolutionary computation — Computer-based problem solving systems that use computational models of evolutionary processes as the key elements in design and implementation. A number of evolutionary computational models have been proposed, including evolutionary algorithms, genetic algorithms, the evolution strategy, evolutionary programming, and artificial life.
  • evolutionary programming — (EP) A stochastic optimisation strategy originally conceived by Lawrence J. Fogel in 1960. An initially random population of individuals (trial solutions) is created. Mutations are then applied to each individual to create new individuals. Mutations vary in the severity of their effect on the behaviour of the individual. The new individuals are then compared in a "tournament" to select which should survive to form the new population. EP is similar to a genetic algorithm, but models only the behavioural linkage between parents and their offspring, rather than seeking to emulate specific genetic operators from nature such as the encoding of behaviour in a genome and recombination by genetic crossover. EP is also similar to an evolution strategy (ES) although the two approaches developed independently. In EP, selection is by comparison with a randomly chosen set of other individuals whereas ES typically uses deterministic selection in which the worst individuals are purged from the population.
  • exponential distribution — a continuous single-parameter distribution used esp when making statements about the length of life of certain materials or waiting times between randomly occurring events. Its density function is p(x) = λe–λx for positive λ and nonnegative x, and it is a special case of the gamma distribution

  • frequent-flyer programme — a plan or system under which frequent flyers earn rewards for being regular customers
  • functional specification — (programming, project)   A description of what a system (e.g. a piece of software) does or should do (but not how it should do it). The functional specification is one of the inputs to the design process. See IEEE/ANSI Std. 610.12-1990.

  • glasgow haskell compiler — (language)   (GHC) A Haskell 1.2 compiler written in Haskell by the AQUA project at Glasgow University, headed by Simon Peyton Jones <[email protected]> throughout the 1990's [started?]. GHC can generate either C or native code for SPARC, DEC Alpha and other platforms. It can take advantage of features of gcc such as global register variables and has an extensive set of optimisations. GHC features an extensible I/O system based on a "monad", in-line C code, fully fledged unboxed data types, incrementally-updatable arrays, mutable reference types, generational garbage collector, concurrent threads. Time and space profiling is also supported. It requires GNU gcc 2.1+ and Perl. GHC runs on Sun-4, DEC Alpha, Sun-3, NeXT, DECstation, HP-PA and SGI. E-mail: <[email protected]>.

  • knowledge representation — The subfield of artificial intelligence concerned with designing and using systems for storing knowledge - facts and rules about some subject. A body of formally represented knowledge is based on a conceptualisation - an abstract view of the world that we wish to represent. In order to manipulate this knowledge we must specify how the abstract conceptualisation is represented as a concrete data structure. An ontology is an explicit specification of a conceptualisation.
