  • genetic fingerprint — DNA fingerprinting.
  • genetic programming — (programming)   (GP) A programming technique which extends the genetic algorithm to the domain of whole computer programs. In GP, populations of programs are genetically bred to solve problems. Genetic programming can solve problems of system identification, classification, control, robotics, optimisation, game playing, and pattern recognition. Starting with a primordial ooze of hundreds or thousands of randomly created programs composed of functions and terminals appropriate to the problem, the population is progressively evolved over a series of generations by applying the operations of Darwinian fitness proportionate reproduction and crossover (sexual recombination).
  • geocentric parallax — the apparent displacement of an observed object due to a change in the position of the observer.
  • gigabits per second — (unit)   (Gbps) A unit of information transfer rate equal to one billion bits per second. Note that, while a gigabit is defined as a power of two (2^30 bits), a gigabit per second is defined as a power of ten (10^9 bits per second, which is slightly less) than 2^30).
  • gloucester old spot — a hardy rare breed of pig, white with a few black markings, that originally lived off windfalls in orchards in the Severn valley
  • graphic workstation — (graphics, computer)   A workstation specifically configured for graphics works such as image manipulation, bitmap graphics ("paint"), and vector graphics ("draw") type applications. Such work requires a powerful CPU and a high resolution display. A graphic workstation is very similar to a CAD workstation and, given the typical specifications of personal computers currently available in 1999, the distinctions are very blurred and are more likely to depend on availability of specific software than any detailed hardware requirements.
  • gregorian telescope — a telescope similar in design to the Cassegrainian telescope but less widely used.
  • grocer's apostrophe — an apostrophe placed before a final s intended to indicate the plural but in fact forming the possessive

  • hyper-nationalistic — a person devoted to nationalism.
  • hyperbolic cosecant — a hyperbolic function that is the reciprocal of hyperbolic sine
  • hyperbolic function — a function of an angle expressed as a relationship between the distances from a point on a hyperbola to the origin and to the coordinate axes, as hyperbolic sine or hyperbolic cosine: often expressed as combinations of exponential functions.
  • hyperbolic geometry — the branch of non-Euclidean geometry that replaces the parallel postulate of Euclidean geometry with the postulate that two distinct lines may be drawn parallel to a given line through a point not on the given line.
