  2. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    The boolean values True and False were added to the language in Python 2.2.1 as constants (subclassed from 1 and 0) and were changed to be full blown keywords in Python 3. The binary comparison operators such as == and > return either True or False.

  3. Packing problems - Wikipedia

    en.wikipedia.org/wiki/Packing_problems

    People are given n unit squares and have to pack them into the smallest possible container, where the container type varies: Packing squares in a square: Optimal solutions have been proven for n from 1-10, 14-16, 22-25, 33-36, 62-64, 79-81, 98-100, and any square integer. The wasted space is asymptotically O(a 3/5).

  4. Determiner spreading - Wikipedia

    en.wikipedia.org/wiki/Determiner_spreading

    In linguistics, determiner spreading (DS), also known as Multiple or Double Determiners [1] is the appearance of more than one determiner associated with a noun phrase, usually marking an adjective as well as the noun itself. [2] The extra determiner has been called an adjectival determiner [3] because determiner spreading is most commonly ...

  6. Determiner - Wikipedia

    en.wikipedia.org/wiki/Determiner

    A determiner combines with a noun to express its reference. [1] [2] Examples in English include articles (the and a), demonstratives (this, that), possessive determiners (my, their), and quantifiers (many, both). Not all languages have determiners, and not all systems of grammatical description recognize them as a distinct category.

    SymPy is an open-source Python library for symbolic computation.It provides computer algebra capabilities either as a standalone application, as a library to other applications, or live on the web as SymPy Live [2] or SymPy Gamma. [3]

  8. Ackermann function - Wikipedia

    en.wikipedia.org/wiki/Ackermann_function

    For small values of m like 1, 2, or 3, the Ackermann function grows relatively slowly with respect to n (at most exponentially). For m ≥ 4 {\displaystyle m\geq 4} , however, it grows much more quickly; even A ( 4 , 2 ) {\displaystyle A(4,2)} is about 2.00353 × 10 19 728 , and the decimal expansion of A ( 4 , 3 ) {\displaystyle A(4,3)} is ...

  9. Pairing function - Wikipedia

    en.wikipedia.org/wiki/Pairing_function

    Whether this is the only polynomial pairing function is still an open question. When we apply the pairing function to k 1 and k 2 we often denote the resulting number as k 1, k 2 . [citation needed] This definition can be inductively generalized to the Cantor tuple function [citation needed]
