  2. Bell number - Wikipedia

    en.wikipedia.org/wiki/Bell_number

    Repeat step three until there is a new row with one more number than the previous row (do step 3 until = +) The number on the left hand side of a given row is the Bell number for that row. (,) Here are the first five rows of the triangle constructed by these rules:

  3. Bell character - Wikipedia

    en.wikipedia.org/wiki/Bell_character

    In the programming language C (created in 1972), and in many languages influenced by it such as Python, the bell character can be placed in a string or character constant with \a. 'a' stands for "alert" or "audible" and was chosen because \b was already used for the backspace character. [4]

  4. Ordered Bell number - Wikipedia

    en.wikipedia.org/wiki/Ordered_Bell_number

    The number of alternative assignments for a given number of workers, taking into account the choices of how many stages to use and how to assign workers to each stage, is an ordered Bell number. [29] As another example, in the computer simulation of origami, the ordered Bell numbers give the number of orderings in which the creases of a crease ...

  6. Partition of a set - Wikipedia

    en.wikipedia.org/wiki/Partition_of_a_set

    The Bell numbers are repeated along both sides of this triangle. The numbers within the triangle count partitions in which a given element is the largest singleton. The number of partitions of an n-element set into exactly k (non-empty) parts is the Stirling number of the second kind S(n, k). The number of noncrossing partitions of an n-element ...

  7. Algorithmic trading - Wikipedia

    en.wikipedia.org/wiki/Algorithmic_trading

    Algorithmic trading is a method of executing orders using automated pre-programmed trading instructions accounting for variables such as time, price, and volume. [1] This type of trading attempts to leverage the speed and computational resources of computers relative to human traders.

  8. Generating function - Wikipedia

    en.wikipedia.org/wiki/Generating_function

    There are various types of generating functions, including ordinary generating functions, exponential generating functions, Lambert series, Bell series, and Dirichlet series. Every sequence in principle has a generating function of each type (except that Lambert and Dirichlet series require indices to start at 1 rather than 0), but the ease ...

  9. Bell polynomials - Wikipedia

    en.wikipedia.org/wiki/Bell_polynomials

    Thus, the number of monomials that appear in the partial Bell polynomial is equal to the number of ways the integer n can be expressed as a summation of k positive integers. This is the same as the integer partition of n into k parts. For instance, in the above examples, the integer 3 can be partitioned into two parts as 2+1 only.
