  2. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    While it was possible to compare disparate types in Python 2 (for example, whether a string was greater-than or less-than an integer), the ordering was undefined; this was considered a historical design quirk and was ultimately removed in Python 3.

  3. Inequality (mathematics) - Wikipedia

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

    The relation not greater than can also be represented by , the symbol for "greater than" bisected by a slash, "not". The same is true for not less than , a ≮ b . {\displaystyle a\nless b.} The notation a ≠ b means that a is not equal to b ; this inequation sometimes is considered a form of strict inequality. [ 4 ]

    is used for an approximation of the much-greater-than sign ≫. ASCII does not have the much greater-than sign. The double greater-than sign is also used for an approximation of the closing guillemet, ». In Java, C, and C++, the operator >> is the right-shift operator.

    In computer science, a relational operator is a programming language construct or operator that tests or defines some kind of relation between two entities.These include numerical equality (e.g., 5 = 5) and inequalities (e.g., 4 ≥ 3).

    A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A000040: Partition numbers P n:

  8. Abundant number - Wikipedia

    en.wikipedia.org/wiki/Abundant_number

    An abundant number whose abundance is greater than any lower number is called a highly abundant number, and one whose relative abundance (i.e. s(n)/n ) is greater than any lower number is called a superabundant number; Every integer greater than 20161 can be written as the sum of two abundant numbers. The largest even number that is not the sum ...

  9. Big M method - Wikipedia

    en.wikipedia.org/wiki/Big_M_method

    For any greater-than constraints, introduce surplus s i and artificial variables a i (as shown below). Choose a large positive Value M and introduce a term in the objective of the form −M multiplying the artificial variables. For less-than or equal constraints, introduce slack variables s i so that all constraints are equalities.
