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 and an ordered pair, respectively. The term "infinite tuple" is occasionally used for "infinite sequences".
Word methods, also known as k-tuple methods, are heuristic methods that are not guaranteed to find an optimal alignment solution, but are significantly more efficient than dynamic programming. These methods are especially useful in large-scale database searches where it is understood that a large proportion of the candidate sequences will have ...
A tuple space is an implementation of the associative memory paradigm for parallel/distributed computing. It provides a repository of tuples that can be accessed concurrently. As an illustrative example, consider that there are a group of processors that produce pieces of data and a group of processors that use the data.
Consider (let us say N) sets of n distinct bit locations are selected randomly. These are the n-tuples.The restriction of a pattern to an n-tuple can be regarded as an n-bit number which, together with the identity of the n-tuple, constitutes a `feature' of the pattern.
is a Pythagorean n-tuple for any tuple of positive integers (m 1, ..., m n) with m 2 1 > m 2 2 + ... + m 2 n. The Pythagorean n-tuple can be made primitive by dividing out by the largest common divisor of its values. Furthermore, any primitive Pythagorean n-tuple a 2 1 + ... + a 2 n = c 2 can be found by this approach.
The body is a set of tuples. A tuple is a collection of n values, where n is the relation's degree, and each value in the tuple corresponds to a unique attribute. [6] The number of tuples in this set is the relation's cardinality. [7]: 17–22 Relations are represented by relational variables or relvars, which can be reassigned.
A deterministic finite automaton M is a 5-tuple, (Q, Σ, δ, q 0, 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; a set of accept states
A pairwise alignment is produced using the k-tuple method.This is a heuristic method that isn't guaranteed to find an optimal solution, but is more efficient than using dynamic programming. Sequences are clustered using the modified mBed method. [22] The mBed method calculates pairwise distance using sequence embedding.
