网页Permuted congruential generator（PCG），其包括一系列变种，统称为 PCG Family，其 2014 年才被提出。 PCG 具有极其良好的特性，可以拥有任意大的周期；良好的统计特性（比 Mersenne Twister 更好，注 6）；高效的计算；同时 PCG 的不可预测性也较前面所说的 PRNG 更好（虽然并 ...
为什么认为线性同余随机数服从均匀分布？ - 知乎
网页首先，让我们澄清一下线性同余法（linear congruential generator，LCG）以及均匀分布的概念：. 线性同余法：LCG是一种生成伪随机数的算法，其递归关系可以表示为：Xn+1 = (aXn + c) mod m，其中Xn是当前的伪随机数，a、c、m 是事先选择的常数。. 这种算法可以生成在 [0, m-1 ...
线性同余方法（LCG）产生随机数 - 知乎 - 知乎专栏
网页线性同余方法（LCG）是一种产生伪随机数的方法。 它是根据递归公式：RandSeed = (A * RandSeed + B) % M. 线性同余法最重要的是定义了三个整数，乘数 A、增量 B和模数 M，其中A, B, M是产生器设定的常数。 LCG的周期最大为 M，但大部分情况都会少于M。 要令LCG达到最大周期，应符合以下条件： B,M互质； M的所有质因数都能整除A-1； 若M是4的倍数，A-1也是； A,B,N [0]都比M小； A,B是正整数。 C 语言实现. 下面给出一种 C 语言 …
What does Linear Congruential mean? - Mathematics Stack Exchange
网页Let's break it down by looking at the definition. An LCG is any PRNG that takes the form. xk+1 = (axk + b) mod M x k + 1 = (a x k + b) mod M. where x0, a x 0, a and b b are some integer parameters, and M M is a large integer only slightly below the largest representable integer on the machine.

网页The meaning of CONGRUENTIAL is having to do with congruence; specifically : characterized by agreement.
SectionII: Linear Congruential GeneratorI - Cornell University
网页One of the most successful random number generators known today are special cases of the following scheme, which is called the linear congruential method. We choose four "magic numbers": X 0 , the starting value; X 0 ≥ 0 . a, the multiplier; a ≥ 0. c, the increment; c ≥ 0. m, the modulus; m > X 0, m > a, m > c.

The Structure of Linear Congruential Sequences - ScienceDirect
网页1972年1月1日 · This chapter discusses the structure of linear congruential sequences and their suitability as a source of random integers in a computer. Every congruential sequence is made up of a block of t < m residues, the effective period of the sequence, followed by translates of that block. A formula is given for the period, effective period, and ...
