In computability theory, the halting problem is the problem of determining, from a description of an arbitrary computer program and an input, whether the program will finish running or continue to run forever. See Computation (nonfiction).
Alan Turing proved in 1936 that a general algorithm to solve the halting problem for all possible program-input pairs cannot exist.
A key part of the proof was a mathematical definition of a computer and program, which became known as a Turing machine; the halting problem is undecidable over Turing machines.
It is one of the first examples of a decision problem.

Asclepius Myrmidon discovers unregistered halting problem, predicts new class of crimes against mathematical constants.
Supervillains Forbidden Ratio and Gnotilus threaten to weaponize new class of Halting problems.
Law-abiding mathematical functions have nothing to fear from Crimes against mathematical constants, say crime authorities.
