2. Superpermutation - Wikipedia

   en.wikipedia.org/wiki/Superpermutation

   Superpermutation. In combinatorial mathematics, a superpermutation on n symbols is a string that contains each permutation of n symbols as a substring. While trivial superpermutations can simply be made up of every permutation concatenated together, superpermutations can also be shorter (except for the trivial case of n = 1) because overlap is ...

3. Fixed-point combinator - Wikipedia

   en.wikipedia.org/wiki/Fixed-point_combinator

   Fixed-point combinator. In combinatory logic for computer science, a fixed-point combinator (or fixpoint combinator ), [1] : p.26 is a higher-order function (i.e. a function which takes a function as argument) that returns some fixed point (a value that is mapped to itself) of its argument function, if one exists.

4. Anonymous function - Wikipedia

   en.wikipedia.org/wiki/Anonymous_function

   Anonymous function. In computer programming, an anonymous function ( function literal, lambda abstraction, lambda function, lambda expression or block) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order ...

5. Anonymity - Wikipedia

   en.wikipedia.org/wiki/Anonymity

   Anonymity. Anonymity [a] describes situations where the acting person's identity is unknown. Some writers have argued that namelessness, though technically correct, does not capture what is more centrally at stake in contexts of anonymity. The important idea here is that a person be non-identifiable, unreachable, or untrackable. [1]

6. Lambda expression - Wikipedia

   en.wikipedia.org/wiki/Lambda_expression

   Lambda expression in computer programming, also called an anonymous function, is a defined function not bound to an identifier. Lambda expression in lambda calculus, a formal system in mathematical logic and computer science for expressing computation by way of variable binding and substitution. Category: Disambiguation pages.

7. Constraint (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Constraint_(mathematics)

   Constraint (mathematics) In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of candidate solutions that satisfy all constraints is called the feasible set.
