  • 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).

  • 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).

  • hamiltonian problem — (computability)   (Or "Hamilton's problem") A problem in graph theory posed by William Hamilton: given a graph, is there a path through the graph which visits each vertex precisely once (a "Hamiltonian path")? Is there a Hamiltonian path which ends up where it started (a "Hamiltonian cycle" or "Hamiltonian tour")? Hamilton's problem is NP-complete. It has numerous applications, sometimes completely unexpected, in computing.
