    en.wikipedia.org/wiki/Plotting_algorithms_for...

    To get colorful images of the set, the assignment of a color to each value of the number of executed iterations can be made using one of a variety of functions (linear, exponential, etc.). One practical way, without slowing down calculations, is to use the number of executed iterations as an entry to a palette initialized at

  3. SymPy - Wikipedia

    en.wikipedia.org/wiki/SymPy

    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]

  4. One-way function - Wikipedia

    en.wikipedia.org/wiki/One-way_function

    Since this function was the first combinatorial complete one-way function to be demonstrated, it is known as the "universal one-way function". The problem of finding a one-way function is thus reduced to proving—perhaps non-constructively—that one such function exists. There also exists a function that is one-way if polynomial-time bounded ...

  5. One-way compression function - Wikipedia

    en.wikipedia.org/wiki/One-way_compression_function

    The Merkle–Damgård hash construction. The boxes labeled [f] are a one-way compression function. A common use of one-way compression functions is in the Merkle–Damgård construction inside cryptographic hash functions. Most widely used hash functions, including MD5, SHA-1 (which is deprecated [2]) and SHA-2 use this construction.

  6. Matplotlib - Wikipedia

    en.wikipedia.org/wiki/Matplotlib

    Matplotlib (portmanteau of MATLAB, plot, and library [3]) is a plotting library for the Python programming language and its numerical mathematics extension NumPy.It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK.

  7. ZX81 character set - Wikipedia

    en.wikipedia.org/wiki/ZX81_character_set

    The character set in the ZX81 was derived from the ZX80 character set. They have mostly the same code points, e.g. for A-Z and 0-9, but the code points are different for the block graphics characters, the symbols ", -, +, *, /, =, >, <, and the BASIC keyword tokens (with many new added). There are also changes to the control characters.

  8. Meijer G-function - Wikipedia

    en.wikipedia.org/wiki/Meijer_G-function

    By choosing one or the other of the two results provided in either formula, one can always prevent the set of parameters in the result from violating the condition a k − b j ≠ 1, 2, 3, ... for k = 1, 2, ..., n and j = 1, 2, ..., m that is imposed by the definition of the G-function. Note that each pair of results becomes unequal in the case ...

  9. Pseudorandom generator theorem - Wikipedia

    en.wikipedia.org/wiki/Pseudorandom_generator_theorem

    One-way permutation → pseudorandom generator A one-way permutation is a one-way function that is also a permutation of the input bits. A pseudorandom generator can be constructed from one-way permutation ƒ as follows: G l: {0,1} l →{0,1} l+1 = ƒ(x).B(x), where B is hard-core predicate of ƒ and "." is a concatenation operator.
