2. List of random number generators - Wikipedia

   en.wikipedia.org/wiki/List_of_random_number...

   Random number generators are important in many kinds of technical applications, including physics, engineering or mathematical computer studies (e.g., Monte Carlo simulations), cryptography and gambling (on game servers). This list includes many common types, regardless of quality or applicability to a given use case.

3. Random.org - Wikipedia

   en.wikipedia.org/wiki/Random.org

   Random.org (stylized as RANDOM.ORG) is a website that produces random numbers based on atmospheric noise. [1] In addition to generating random numbers in a specified range and subject to a specified probability distribution, which is the most commonly done activity on the site, it has free tools to simulate events such as flipping coins ...

4. Verbal arithmetic - Wikipedia

   en.wikipedia.org/wiki/Verbal_arithmetic

   Verbal arithmetic, also known as alphametics, cryptarithmetic, cryptarithm or word addition, is a type of mathematical game consisting of a mathematical equation among unknown numbers, whose digits are represented by letters of the alphabet. The goal is to identify the value of each letter. The name can be extended to puzzles that use non ...

5. Nihilist cipher - Wikipedia

   en.wikipedia.org/wiki/Nihilist_cipher

   Unlike basic Nihilist, the additive was added by non-carrying addition (digit-wise addition modulo 10), thus producing a more uniform output which doesn't leak as much information. More importantly, the additive was generated not through a keyword, but by selecting lines at random from almanacs of industrial statistics.

6. Pseudorandom number generator - Wikipedia

   en.wikipedia.org/wiki/Pseudorandom_number_generator

   Pseudorandom number generator. A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), [1] is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. The PRNG-generated sequence is not truly random, because it is completely ...

7. Gold code - Wikipedia

   en.wikipedia.org/wiki/Gold_code

   Gold code. A Gold code, also known as Gold sequence, is a type of binary sequence, used in telecommunications (CDMA) [1] and satellite navigation (GPS). [2] Gold codes are named after Robert Gold. [3][4] Gold codes have bounded small cross-correlations within a set, which is useful when multiple devices are broadcasting in the same frequency range.

8. Random number table - Wikipedia

   en.wikipedia.org/wiki/Random_number_table

   Random number tables have been used in statistics for tasks such as selected random samples. This was much more effective than manually selecting the random samples (with dice, cards, etc.). Nowadays, tables of random numbers have been replaced by computational random number generators. If carefully prepared, the filtering and testing processes ...

9. Pseudorandom noise - Wikipedia

   en.wikipedia.org/wiki/Pseudorandom_noise

   A pseudo-noise code (PN code) or pseudo-random-noise code (PRN code) is one that has a spectrum similar to a random sequence of bits but is deterministically generated. The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences, Gold codes, Kasami codes, and Barker codes. [4]
