  • free-body diagram — A free-body diagram is a diagram of a structure in which all supports are replaced by forces.
  • genetic algorithm — (GA) An evolutionary algorithm which generates each individual from some encoded form known as a "chromosome" or "genome". Chromosomes are combined or mutated to breed new individuals. "Crossover", the kind of recombination of chromosomes found in sexual reproduction in nature, is often also used in GAs. Here, an offspring's chromosome is created by joining segments choosen alternately from each of two parents' chromosomes which are of fixed length. GAs are useful for multidimensional optimisation problems in which the chromosome can encode the values for the different variables being optimised.
  • geomagnetic storm — magnetic storm.
  • glymphatic system — Anatomy. the system or process by which cerebrospinal fluid moves through channels formed by glia, cleansing the mammalian brain of harmful waste.
  • green book cd-rom — A standard CD-ROM format developed by Philips for CD-i. It is ISO 9660 compliant and uses mode 2 form 2 addressing. It can only be played on drives which are XA (Extended Architecture) compatible. Many Green Book discs contain CD-i applications which can only be played on a CD-i player but many others contain films or music videos. Video CDs in Green Book format are normally labelled "Digital Video on CD" Green Book was obsoleted by White book CD-ROM in March 1994.
  • gridiron pendulum — a clock pendulum having, as part of its shaft, an arrangement of brass and steel rods having different coefficients of expansion, such that the pendulum has the same length at any temperature.

  • memetic algorithm — (algorithm)   A genetic algorithm or evolutionary algorithm which includes a non-genetic local search to improve genotypes. The term comes from the Richard Dawkin's term "meme". One big difference between memes and genes is that memes are processed and possibly improved by the people that hold them - something that cannot happen to genes. It is this advantage that the memetic algorithm has over simple genetic or evolutionary algorithms. These algorithms are useful in solving complex problems, such as the "Travelling Salesman Problem," which involves finding the shortest path through a large number of nodes, or in creating artificial life to test evolutionary theories. Memetic algorithms are one kind of metaheuristic. (07 July 1997)
