  • 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.

  • ideogrammatically — In terms of, or by means of, ideograms.
  • image recognition — (graphics, artificial intelligence)   The identification of objects in an image. This process would probably start with image processing techniques such as noise removal, followed by (low-level) feature extraction to locate lines, regions and possibly areas with certain textures. The clever bit is to interpret collections of these shapes as single objects, e.g. cars on a road, boxes on a conveyor belt or cancerous cells on a microscope slide. One reason this is an AI problem is that an object can appear very different when viewed from different angles or under different lighting. Another problem is deciding what features belong to what object and which are background or shadows etc. The human visual system performs these tasks mostly unconsciously but a computer requires skillful programming and lots of processing power to approach human performance.
  • immigrant workers — people who work in a country they arrived to in order to settle there
  • impossible figure — a picture of an object that at first sight looks three-dimensional but cannot be a two-dimensional projection of a real three-dimensional object, for example a picture of a staircase that re-enters itself while appearing to ascend continuously

  • intergovernmental — involving two or more governments or levels of government.
  • intragovernmental — Within a government.
  • irrigation system — a system of supplying (land) with water by means of artificial canals, ditches, etc, esp to promote the growth of food crops

  • langmuir isotherm — A Langmuir isotherm is a classical relationship between the concentrations of a solid and a fluid, used to describe a state of no change in the sorption process.
  • let something rip — If you let something rip, you do it as quickly or as forcefully as possible. You can say 'let it rip' or 'let her rip' to someone when you want them to make a vehicle go as fast as it possibly can.
  • light mineral oil — a colorless, oily, almost tasteless, water-insoluble liquid, usually of either a standard light density (light mineral oil) or a standard heavy density (heavy mineral oil) consisting of mixtures of hydrocarbons obtained from petroleum by distillation: used chiefly as a lubricant, in the manufacture of cosmetics, and in medicine as a laxative.

  • margaret hamilton — (person)   (born 1936-08-17) A computer scientist, systems engineer and business owner, credited with coining the term software engineering. Margaret Hamilton published over 130 papers, proceedings and reports about the 60 projects and six major programs in which she has been involved. In 1965 she became Director of Software Programming at MIT's Charles Stark Draper Laboratory and Director of the Software Engineering Division of the MIT Instrumentation Laboratory, which developed on-board flight software for the Apollo space program. At NASA, Hamilton pioneered the Apollo on-board guidance software that navigated to and landed on the Moon and formed the basis for software used in later missions. At the time, programming was a hands-on, engineering descipline; computer science and software engineering barely existed. Hamilton produced innovations in system design and software development, enterprise and process modelling, development paradigms, formal systems modelling languages, system-oriented objects for systems modelling and development, automated life-cycle environments, software reliability, software reuse, domain analysis, correctness by built-in language properties, open architecture techniques for robust systems, full life-cycle automation, quality assurance, seamless integration, error detection and recovery, man-machine interface systems, operating systems, end-to-end testing and life-cycle management. She developed concepts of asynchronous software, priority scheduling and Human-in-the-loop decision capability, which became the foundation for modern, ultra-reliable software design. The Apollo 11 moon landing would have aborted when spurious data threatened to overload the computer, but thanks to the innovative asynchronous, priority based scheduling, it eliminated the unnecessary processing and completed the landing successfully. In 1986, she founded Hamilton Technologies, Inc., developed around the Universal Systems Language and her systems and software design paradigm of Development Before the Fact (DBTF).
  • marriage ceremony — official part of a wedding
  • medicochirurgical — pertaining to medicine and surgery.
  • 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)
