  • galloping-ghost — Harold ("Red"; "the Galloping Ghost") 1903–1991, U.S. football player.
  • gigantopithecus — a genus of extinct ape of southern Asia existing during the Pliocene and Pleistocene epochs, known only from very large fossil jaws and teeth and believed to be perhaps the biggest hominoid that ever lived.
  • golden pheasant — an Asiatic pheasant, Chrysolophus pictus, having brilliant scarlet, orange, gold, green, and black plumage.
  • golden samphire — a Eurasian coastal plant, Inula crithmoides, with fleshy leaves and yellow flower heads: family Asteraceae (composites)
  • gramophonically — in a gramophonic manner
  • grandparenthood — The state of being a grandparent.
  • graph colouring — (application)   A constraint-satisfaction problem often used as a test case in research, which also turns out to be equivalent to certain real-world problems (e.g. register allocation). Given a connected graph and a fixed number of colours, the problem is to assign a colour to each node, subject to the constraint that any two connected nodes cannot be assigned the same colour. This is an example of an NP-complete problem. See also four colour map theorem.
  • graph reduction — A technique invented by Chris Wadsworth where an expression is represented as a directed graph (usually drawn as an inverted tree). Each node represents a function call and its subtrees represent the arguments to that function. Subtrees are replaced by the expansion or value of the expression they represent. This is repeated until the tree has been reduced to a value with no more function calls (a normal form). In contrast to string reduction, graph reduction has the advantage that common subexpressions are represented as pointers to a single instance of the expression which is only reduced once. It is the most commonly used technique for implementing lazy evaluation.
  • gynandromorphic — (of an organism) Having male and female characteristics.
  • halting problem — The problem of determining in advance whether a particular program or algorithm will terminate or run forever. The halting problem is the canonical example of a provably unsolvable problem. Obviously any attempt to answer the question by actually executing the algorithm or simulating each step of its execution will only give an answer if the algorithm under consideration does terminate, otherwise the algorithm attempting to answer the question will itself run forever. Some special cases of the halting problem are partially solvable given sufficient resources. For example, if it is possible to record the complete state of the execution of the algorithm at each step and the current state is ever identical to some previous state then the algorithm is in a loop. This might require an arbitrary amount of storage however. Alternatively, if there are at most N possible different states then the algorithm can run for at most N steps without looping. A program analysis called termination analysis attempts to answer this question for limited kinds of input algorithm.
