  2. Map (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Map_(higher-order_function)

    Below, there is view of each step of the mapping process for a list of integers X = [0, 5, 8, 3, 2, 1] mapping into a new list X' according to the function () = + : . View of processing steps when applying map function on a list

  3. Decidability of first-order theories of the real numbers

    en.wikipedia.org/wiki/Decidability_of_first...

    The theory of real closed fields is the theory in which the primitive operations are multiplication and addition; this implies that, in this theory, the only numbers that can be defined are the real algebraic numbers. As proven by Tarski, this theory is decidable; see Tarski–Seidenberg theorem and Quantifier elimination.

  4. Rice's theorem - Wikipedia

    en.wikipedia.org/wiki/Rice's_theorem

    For example, Rice's theorem implies that in dynamically typed programming languages which are Turing-complete, it is impossible to verify the absence of type errors. On the other hand, statically typed programming languages feature a type system which statically prevents type errors.

  5. Boundary-value analysis - Wikipedia

    en.wikipedia.org/wiki/Boundary-value_analysis

    The boundary between two partitions is the place where the behavior of the application changes and is not a real number itself. The boundary value is the minimum (or maximum) value that is at the boundary. The number 0 is the maximum number in the first partition, the number 1 is the minimum value in the second partition, both are boundary values.

  6. Lodash - Wikipedia

    en.wikipedia.org/wiki/Lodash

    Lodash is a JavaScript library that helps programmers write more concise and maintainable JavaScript. It can be broken down into several main areas: Utilities: for simplifying common programming tasks such as determining type as well as simplifying math operations.

  7. Completeness of the real numbers - Wikipedia

    en.wikipedia.org/wiki/Completeness_of_the_real...

    The real numbers can be defined synthetically as an ordered field satisfying some version of the completeness axiom.Different versions of this axiom are all equivalent in the sense that any ordered field that satisfies one form of completeness satisfies all of them, apart from Cauchy completeness and nested intervals theorem, which are strictly weaker in that there are non Archimedean fields ...

  8. Undefined (mathematics) - Wikipedia

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

    For example, the imaginary number is undefined within the set of real numbers. So it is meaningless to reason about the value, solely within the discourse of real numbers. However, defining the imaginary number i {\displaystyle i} to be equal to − 1 {\displaystyle {\sqrt {-1}}} , allows there to be a consistent set of mathematics referred to ...

  9. Tent map - Wikipedia

    en.wikipedia.org/wiki/Tent_map

    For example, when μ is 1.5 there is a fixed point at x = 0.6 (since 1.5(10.6) = 0.6) but starting at x = 0.61 we get … If μ is between 1 and the square root of 2 the system maps a set of intervals between μ − μ 2 /2 and μ/2 to themselves. This set of intervals is the Julia set of the map – that is, it is the smallest invariant ...
