  2. Deterministic finite automaton - Wikipedia

    en.wikipedia.org/wiki/Deterministic_finite_automaton

    A deterministic finite automaton M is a 5- tuple, (Q, Σ, δ, q0, F), consisting of. a finite set of states Q. a finite set of input symbols called the alphabet Σ. a transition function δ: Q × Σ → Q. an initial or start state q 0 ∈ Q {\displaystyle q_ {0}\in Q} a set of accept states F ⊆ Q {\displaystyle F\subseteq Q}

  3. Tuple - Wikipedia

    en.wikipedia.org/wiki/Tuple

    Tuple. In mathematics, a tuple is a finite sequence or ordered list of numbers or, more generally, mathematical objects, which are called the elements of the tuple. An n-tuple is a tuple of n elements, where n is a non-negative integer. There is only one 0-tuple, called the empty tuple. A 1-tuple and a 2-tuple are commonly called a singleton ...

  4. Iterative Stencil Loops - Wikipedia

    en.wikipedia.org/wiki/Iterative_Stencil_Loops

    Since the stencil is the same for each element, the pattern of data accesses is repeated. [4] More formally, we may define ISLs as a 5-tuple (,,,,) with the following meaning: [3] = = [, …,] is the index set. It defines the topology of the array.

  5. Ordered pair - Wikipedia

    en.wikipedia.org/wiki/Ordered_pair

    Ordered pairs are also called 2-tuples, or sequences (sometimes, lists in a computer science context) of length 2. Ordered pairs of scalars are sometimes called 2-dimensional vectors. (Technically, this is an abuse of terminology since an ordered pair need not be an element of a vector space.)

  6. Permutation - Wikipedia

    en.wikipedia.org/wiki/Permutation

    [5] The rule to determine the number of permutations of n objects was known in Indian culture around ... If the set S has n elements, the number of k-tuples over S is

  7. Finitary relation - Wikipedia

    en.wikipedia.org/wiki/Finitary_relation

    Finitary relation. In mathematics, a finitary relation over a sequence of sets X1, ..., Xn is a subset of the Cartesian product X1 × ... × Xn; that is, it is a set of n -tuples (x1, ..., xn), each being a sequence of elements xi in the corresponding Xi. [1][2][3] Typically, the relation describes a possible connection between the elements of ...

  8. Real coordinate space - Wikipedia

    en.wikipedia.org/wiki/Real_coordinate_space

    An element of R n is thus a n-tuple, and is written (,, …,) where each x i is a real number. So, in multivariable calculus , the domain of a function of several real variables and the codomain of a real vector valued function are subsets of R n for some n .

  9. Direct sum - Wikipedia

    en.wikipedia.org/wiki/Direct_sum

    The direct sum is an operation between structures in abstract algebra, a branch of mathematics. It is defined differently, but analogously, for different kinds of structures. As an example, the direct sum of two abelian groups and is another abelian group consisting of the ordered pairs where and . To add ordered pairs, we define the sum to be ...
