A decision problem whose input consists of strings or more complex values is formalized as the set of numbers that, via a specific Gödel numbering, correspond to inputs that satisfy the decision problem's criteria. A decision problem A is called decidable or effectively solvable if the formalized set of A is a recursive set.
In computability theory, an undecidable problem is a decision problem for which an effective method (algorithm) to derive the correct answer does not exist. More formally, an undecidable problem is a problem whose language is not a recursive set ; see the article Decidable language .
Undecidable problem in computer science and mathematical logic, a decision problem that no algorithm can decide, formalized as an undecidable language or undecidable set "Undecidable", sometimes also used as a synonym of independent, something that can neither be proved nor disproved within a mathematical theory
The solution depends on how the problem is framed and vice versa (i.e., the problem definition depends on the solution) Stakeholders have radically different world views and different frames for understanding the problem. The constraints that the problem is subject to and the resources needed to solve it change over time.
A word, phrase, or affix that specifies the reference of a noun or noun phrase, such as "the", "some", "every". deterministic polynomial time A complexity class (P) consisting of decision problems that can be solved by a deterministic Turing machine in polynomial time.
