Päätettävyys
Päätettävyys, also known as decidability, is a concept in theoretical computer science and logic that refers to the ability to determine, through an algorithm, whether a given statement or problem has a solution. A problem is considered decidable if there exists an algorithm that can always produce a correct answer, either "yes" or "no," for any input within a finite amount of time. This algorithm must terminate for all possible inputs, providing a definitive answer.
In contrast, a problem is undecidable if no such algorithm exists. The concept of decidability is closely
Decidability is a fundamental concept in the study of computation and complexity. It helps classify problems
