Python uses the following syntax to express list comprehensions over finite lists: S = [ 2 * x for x in range ( 100 ) if x ** 2 > 3 ] A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which ...
If we associate with each item of the input a uniformly generated random number, the k items with the largest (or, equivalently, smallest) associated values form a simple random sample. [3] A simple reservoir-sampling thus maintains the k items with the currently largest associated values in a priority queue.
A random-access list is a list with support for fast random access to read or modify any element in the list. [7] One possible implementation is a skew binary random-access list using the skew binary number system , which involves a list of trees with special properties; this allows worst-case constant time head/cons operations, and worst-case ...
A simple algorithm to generate a permutation of n items uniformly at random without retries, known as the Fisher–Yates shuffle, is to start with any permutation (for example, the identity permutation), and then go through the positions 0 through n − 2 (we use a convention where the first element has index 0, and the last element has index n − 1), and for each position i swap the element ...
|1=‥|2=‥| N = → The items to return. |same=y Set to a truthy value for all calls with this parameter set and the same number of items to return the same item. There used to be a |range= parameter, but this is no longer needed.
{{#invoke:random|list|list item 1|list item 2|list item 3|...|sep=separator|limit=number of items to display|same=yes}} Named parameters |sep= or |separator= - an optional separator for the list items. Some values are special; see the table below. |limit= - the maximum number of list items to display. The lowest possible is 0 and the highest ...
Random priority (RP), [1] also called Random serial dictatorship (RSD), [2] is a procedure for fair random assignment - dividing indivisible items fairly among people. Suppose partners have to divide (or fewer) different items among them. Since the items are indivisible, some partners will necessarily get the less-preferred items (or no items ...
