- electra paradox — the supposed paradox that one may know something to be true of an object under one description but not another, as when Electra knew that Orestes was her brother but not that the man before her was her brother although he was Orestes. This shows the predicate "knows" to be intensional, that Electra's knowledge here is de dicto, and that the statement of it yields an opaque context

- grandparenthood — The state of being a grandparent.
- grapes of wrath — a novel (1939) by John Steinbeck.
- 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.
- graviperception — the perception of gravity by plants
- group separator — (character) (GS) ASCII character 29.
- group therapist — a psychotherapist who conducts group therapy
- 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.
