  • 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.
  • geomagnetic equator — an imaginary line on the earth's surface, the plane of which passes through the center and is midway between the geomagnetic poles.
  • gestational carrier — surrogate mother (def 3).
  • 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).
  • glyceryl trinitrate — nitroglycerin.
  • grammatical meaning — the meaning of an inflectional morpheme or of some other syntactic device, as word order.
  • grandfather's chair — wing chair.
  • great wall of china — a system of fortified walls with a roadway along the top, constructed as a defense for China against the nomads of the regions that are now Mongolia and Manchuria: completed in the 3rd century b.c., but later repeatedly modified and rebuilt. 2000 miles (3220 km) long.

  • halt and catch fire — (humour, processor)   (HCF) Any of several undocumented and semi-mythical machine instructions with destructive side-effects, supposedly included for test purposes on several well-known architectures going as far back as the IBM 360. The Motorola 6800 microprocessor was the first for which an HCF opcode became widely known. This instruction caused the processor to read every memory location sequentially until reset.

  • holy innocents' day — December 28, a day of religious observance commemorating the slaughter of the children of Bethlehem by Herod's order.
  • horizontal encoding — (processor)   An instruction set where each field (a bit or group of bits) in an instruction word controls some functional unit or gate directly, as opposed to vertical encoding where instruction fields are decoded (by hard-wired logic or microcode) to produce the control signals. Horizontal encoding allows all possible combinations of control signals (and therefore operations) to be expressed as instructions whereas vertical encoding uses a shorter instruction word but can only encode those combinations of operations built into the decoding logic. An instruction set may use a mixture of horizontal and vertical encoding within each instruction. Because an architecture using horizontal encoding typically requires more instruction word bits it is sometimes known as a very long instruction word (VLIW) architecture.
