  2. Lazy evaluation - Wikipedia

    en.wikipedia.org/wiki/Lazy_evaluation

    In Python 3.x the range() function [28] returns a generator which computes elements of the list on demand. Elements are only generated when they are needed (e.g., when print(r[3]) is evaluated in the following example), so this is an example of lazy or deferred evaluation:

  3. List update problem - Wikipedia

    en.wikipedia.org/wiki/List_update_problem

    The List Update or the List Access problem is a simple model used in the study of competitive analysis of online algorithms.Given a set of items in a list where the cost of accessing an item is proportional to its distance from the head of the list, e.g. a linked List, and a request sequence of accesses, the problem is to come up with a strategy of reordering the list so that the total cost of ...

  4. List comprehension - Wikipedia

    en.wikipedia.org/wiki/List_comprehension

    Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.

    Hermes Project: C++/Python library for rapid prototyping of space- and space-time adaptive hp-FEM solvers. IML++ is a C++ library for solving linear systems of equations, capable of dealing with dense, sparse, and distributed matrices. IT++ is a C++ library for linear algebra (matrices and vectors), signal processing and communications ...

  6. Kendall tau distance - Wikipedia

    en.wikipedia.org/wiki/Kendall_tau_distance

    Kendall tau distance is also called bubble-sort distance since it is equivalent to the number of swaps that the bubble sort algorithm would take to place one list in the same order as the other list. The Kendall tau distance was created by Maurice Kendall .

    1985, StarOffice for MS-DOS, later becoming OpenOffice.org then currently LibreOffice and Collabora Online. 1985, 20/20, for MS-DOS, competitor to 1-2-3 with database integration, real-time data updating, multiplatform. 1986, VP Planner for MS-DOS, similar in look and feel to Lotus 1-2-3, but included 5 level multi-dimensional database [12]

  8. Backward chaining - Wikipedia

    en.wikipedia.org/wiki/Backward_chaining

    If X croaks and X eats flies – Then X is a frog; If X chirps and X sings – Then X is a canary; If X is a frog – Then X is green; If X is a canary – Then X is yellow; With backward reasoning, an inference engine can determine whether Fritz is green in four steps. To start, the query is phrased as a goal assertion that is to be proven ...

  9. Simon's problem - Wikipedia

    en.wikipedia.org/wiki/Simon's_problem

    Simon's problem considers access to a function : {,} {,}, as implemented by a black box or an oracle. This function is promised to be either a one-to-one function, or a two-to-one function; if is two-to-one, it is furthermore promised that two inputs and ′ evaluate to the same value if and only if and ′ differ in a fixed set of bits. I.e.,
