In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance.
Whereas the singleton allows only one instance of a class to be created, the multiton pattern allows for the controlled creation of multiple instances, which it manages through the use of a map. Rather than having a single instance per application (e.g. the java.lang.Runtime object in the Java programming language ) the multiton pattern instead ...
In coding theory, the Singleton bound, named after Richard Collom Singleton, is a relatively crude upper bound on the size of an arbitrary block code with block length , size and minimum distance . It is also known as the Joshibound [ 1 ] proved by Joshi (1958) and even earlier by Komamiya (1953) .

In some cases, an inability to balance is referred to as a symptom known as ataxia. But ataxia can also be its own condition or disease.
in Kotlin, Unit is a singleton with only one value: the Unit object. In Ruby, nil is the only instance of the NilClass class. In C++, the std::monostate unit type was added in C++17. Before that, it is possible to define a custom unit type using an empty struct such as struct empty{}.
