무작위 정수 소개

Before machines, random numbers were a publishing problem. L. H. C. Tippett produced the first widely used table in 1927: 41,600 digits, which he extracted from the area figures of a 1925 census report rather than generating from scratch. M. G. Kendall and B. Babington Smith were not satisfied that borrowed digits were random enough, so they built a randomising machine of their own design, published the statistical tests they thought a table should pass, and released 100,000 digits in 1939. The RAND Corporation went further in 1955 with A Million Random Digits with 100,000 Normal Deviates, whose contents came from an electronic roulette wheel and had to be de-biased before the book could go to press.

Hardware ran in parallel with paper. On 1 June 1957 the British Post Office switched on ERNIE — Electronic Random Number Indicator Equipment — to draw Premium Bond winners. It was built at the Dollis Hill research station by engineers including Tommy Flowers, who had designed the wartime Colossus, and it took its digits from electrical noise rather than arithmetic. The first draw kept it running for more than fifty hours.

The arithmetic approach that now dominates began with Derrick Henry Lehmer's linear congruential generator, proposed in 1949. It was cheap, and wrong in a specific way: in 1968 George Marsaglia showed, in a Proceedings of the National Academy paper titled "Random Numbers Fall Mainly in the Planes", that consecutive outputs of such generators lie on a lattice of hyperplanes. IBM's widely distributed RANDU was the notorious case — with multiplier 65539 and modulus 2^31, every triple of its outputs falls on just fifteen planes inside the unit cube, which quietly undermined simulation work for years.

Drawing without replacement has its own lineage. The shuffle now named for Ronald Fisher and Frank Yates appeared in their 1938 statistical tables as a pencil-and-paper procedure; Richard Durstenfeld published the in-place computer version in 1964.

주요 성질

Every value is drawn independently and uniformly, so each of the max − min + 1 possible outcomes has the same probability.
With duplicates allowed, drawing n numbers from a range of N values has N^n equally likely ordered outcomes.
The expected mean of a uniform draw from a to b is (a + b) / 2, and the variance is ((b − a + 1)² − 1) / 12.
The birthday problem applies to repeats: just 23 independent draws from 1–365 already give a better-than-even chance that two of them match.
With duplicates switched off and the count equal to the range size, the output is a uniformly random permutation of the whole range.
This page maps the generator’s 32-bit word onto your range by rejection sampling, which removes the modulo bias that a plain remainder introduces whenever the range size does not divide 2³² exactly.
The range is capped at ±1,000,000,000 so every result is an exact integer, well inside JavaScript’s safe range of ±(2⁵³ − 1).
The underlying generator is mulberry32, a deterministic PRNG. It is reproducible by design and therefore unsuitable for keys, passwords, or anything else that depends on being unpredictable.
