- 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. The halting problem is undecidable, meaning that no general algorithm exists that solves the halting problem for all possible program–input pairs. The problem comes up often in discussions of computability since it demonstrates that some functions are mathematically definable but not computable.

Prince Edward Island (PEI; French: Île-du-Prince-Édouard; Scottish Gaelic: Eilean a’ Phrionnsa; colloquially known as The Island) is one of the thirteen provinces and territories of Canada. While it is the smallest province in terms of land area and population, it is the most densely populated. The island has several nicknames: “Garden of the Gulf”, “Birthplace of Confederation” and “Cradle of Confederation”. Its capital and largest city is Charlottetown. It is one of the three Maritime provinces and one of the four Atlantic provinces.
