  2. Help:Sortable tables - Wikipedia

    en.wikipedia.org/wiki/Help:Sortable_tables

    The ! indicates cells that are header cells. In order for a table to be sortable, the first row(s) of a table need to be entirely made up out of these header cells. You can learn more about the basic table syntax by taking the Introduction to tables for source editing.

    en.wikipedia.org/wiki/Help:Wikitext

    Making a reference citing a printed or online source can be accomplished by using the <ref> wiki markup tags. Inside these tags details about the reference are added. Details about the citation can be provided using a structure provided by various templates; the table below lists some typical citation components.

    {| |+ The table's caption |- | cell code goes here |- | next row cell code goes here | next cell code goes here |} Cells can be separated with either a new line and a single bar, or by a double bar "||" on the same line. Both produce the same output:

  5. Maximum and minimum - Wikipedia

    en.wikipedia.org/wiki/Maximum_and_minimum

    Similarly, the function has a global (or absolute) minimum point at x ∗, if f(x ∗) ≤ f(x) for all x in X. The value of the function at a maximum point is called the maximum value of the function, denoted max ( f ( x ) ) {\displaystyle \max(f(x))} , and the value of the function at a minimum point is called the minimum value of the ...

  6. Select (SQL) - Wikipedia

    en.wikipedia.org/wiki/Select_(SQL)

    SQL includes operators and functions for calculating values on stored values. SQL allows the use of expressions in the select list to project data, as in the following example, which returns a list of books that cost more than 100.00 with an additional sales_tax column containing a sales tax figure calculated at 6% of the price.

  7. Loss function - Wikipedia

    en.wikipedia.org/wiki/Loss_function

    In many applications, objective functions, including loss functions as a particular case, are determined by the problem formulation. In other situations, the decision maker’s preference must be elicited and represented by a scalar-valued function (called also utility function) in a form suitable for optimization — the problem that Ragnar Frisch has highlighted in his Nobel Prize lecture. [4]

  8. Automatic Reference Counting - Wikipedia

    en.wikipedia.org/wiki/Automatic_Reference_Counting

    Automatic Reference Counting (ARC) is a memory management feature of the Clang compiler providing automatic reference counting for the Objective-C and Swift programming languages. At compile time, it inserts into the object code messages retain and release [ 1 ] [ 2 ] which increase and decrease the reference count at run time, marking for ...

  9. Absolute continuity - Wikipedia

    en.wikipedia.org/wiki/Absolute_continuity

    In calculus and real analysis, absolute continuity is a smoothness property of functions that is stronger than continuity and uniform continuity. The notion of absolute continuity allows one to obtain generalizations of the relationship between the two central operations of calculus — differentiation and integration .
