Negative Qualities Statistically mediocre Although the standard variant does pass TestU01's BigCrush battery, that isn't much of an achievement given bits of internal state—a simple LCG passes with 88 bits of internal state!

Minstd and Unix rand Minstd and rand some implementations are both examples of linear congruential generators with a non-power-of-two modulus. There are many more feedback arrangements for various-length LSFRs that produce maximum-length sequences, but don't fiddle with the feedback sequences without the proper mathematical theory. There are various other decimation techniques as well. The random number generator that came with your compiler may have lousy statistical properties and repeat after only 16, bits, but at least it can reproduce the same sequence on demand. Negative Qualities Statistically mediocre Although the standard variant does pass TestU01's BigCrush battery, that isn't much of an achievement given bits of internal state—a simple LCG passes with 88 bits of internal state! For applications where this is not a requirement, XORing the output of this generator with some system-dependent register the low-order bit of some clock or garbage collection register, for examplewill produce a sequence so close to random for most applications that it might as well be. I'll spare you the number theory in this article see almost any cryptography text for detailsand have taken the liberty of choosing three maximum-length LSFRs for my generator, one each of 32 bits, 31 bits, and 29 bits.
However, your typical computer programmer will find this sort of specialized hardware out of reach.

ChaCha20, being newer, has received less scrutiny from the cryptographic community than Arc4. Negative Qualities Fails some statistical testswith as few as 45, numbers. This, of course, assumes that the sequence has a flat distribution. Anything that is periodic is, by definition, predictable. Put the same stuff into two identical computers, and the same stuff comes out of both of them. See the XorShift Wikipedia page for more details. These properties can be empirically measured and then compared to statistical expectations using a chi-square test.

Has a much smaller period than might be inferred from the size of the generator state. Fewer rounds result in poor statistical performance; ChaCha2 fails statistical tests badly, and ChaCha4 passes TestU01 but sophisticated mathematical analysis has shown it to exhibit some bias.
ChaCha8 and higher are believed to be good. Nevertheless, ChaCha needs to go to more work to achieve satisfactory statistical quality than many other generators. ChaCha20, being newer, has received less scrutiny from the cryptographic community than Arc4.
Unlike some generators with a very large period, it does not provide k - dimensional equidistribution. Multithreaded programs must share the global RNG, and contend for the spin lock that protects it. Unix drand48 , Java's java.

Negative Qualities Fairly short period bit version only Predictable. After producing just one random number, we can completely predict its output. Fails many statistical tests Technically not uniform — zero will be produced once less often than every other output bit XorShift should usually not be used to produce bit numbers, because it only produces each number once, and never produces zero.

Neutral Qualities Can perform party tricks, like creating a generator which will produce exactly 3,,,,,,, random numbers, and then suddenly output a Zip file containing Hamlet. That would require 16 GB of memory.
Or, instead of starting with an array of all possible bit integers, we could start with an initial sequence of any sorted integers. In an attempt to span the available range of bit values, we could even model the initial sequence as a Poisson process.
All of the above approaches either run in non-linear time, or require large amounts of storage. Several of them would be workable for a sequence of just integers, but it got me thinking whether a more efficient approach, which scales up to any sequence length, is possible.
The ideal PRNG for this problem is one which would generate a unique, random integer the first 2 32 times we call it, then repeat the same sequence the next 2 32 times it is called, ad infinitum. In other words, a repeating cycle of 2 32 values.
That way, we could begin the PRNG at any point in the cycle, always having the guarantee that the next 2 32 values are repeat-free. One way to implement such a PRNG is to define a one-to-one function on the integers — a function which maps each bit integer to another, uniquely.
We could even begin the input sequence at any value. Seems like a nice tool for building our custom PRNG. In the case of our custom PRNG, we want a permutation which works on the entire range of bit integers. If you want a sequence which is 0 three-quarters of the time and 1 one-quarter of the time, my advice is to start with a flat sequence and then manipulate it -- it's much easier that way.
A lot of effort has gone into producing good pseudo-random sequences on computers. Generators abound in the academic literature, along with various tests of randomness. All of these generators are periodic there's no escaping that, but with potential periods of 2 bits and higher, they can be used for most simulations that expect to terminate before the next ice age.
In the October issue of Communications of the ACM, a detailed and comprehensive article by Pierre L'Ecuyer discussed a family of linear congruential generators and other pseudo-random sequence generators based on them.
The simplest of these have the form: Many of the generators in this family can seriously bottleneck a complex program. They can require a large number of multiplications and divisions per cycle. The pseudo-random sequence generator described in this article is both fast and statistically sound.
Its period is long enough for most applications, and it has been optimized for fast execution on bit microprocessors. In addition, it has no machine-dependent operations, so a specific sequence generated on one machine will be exactly the same as a sequence generated on another.
The generator produces a pseudo-random sequence of bits. If you need larger random numbers, take a series of bits and combine them. Three sequential bits is a random number between 0 and 7. If you collect 4 bits in sequence and try again if you get a number greater than, then you have a random number between 0 and 9.
Feedback shift registers have been generating random sequences for a long time. They're discussed in Numerical Recipes in C and by Knuth. Basically, they consist of a shift register and a feedback sequence.
Everytime a random bit is needed, all the bits in the register shift 1 bit to the right the low-order bit falls into the bit bucket, and a new high-order bit is calculated as a function of the other bits and appended to the left side of the register.
The generator returns the low-order bit. An LSFR is a special case of a feedback shift register, where the generator calculates the new high-order bit by taking the XOR of some subset of the bits in the register see Figure 1.
In theory, an n-bit LSFR can generate a 2 n bit pseudo-random sequence before repeating. To do this, the shift register must cycle through all 2 n -1 combinations. It's 2 n -1 and not 2 n because a shift register filled with 0s will cause the LSFR to output a never-ending stream of 0s, which is not particularly useful.
Only certain feedback sequences produce LSFRs with this maximum-length sequence. I'll spare you the number theory in this article see almost any cryptography text for details, and have taken the liberty of choosing three maximum-length LSFRs for my generator, one each of 32 bits, 31 bits, and 29 bits.
LSFRs are competent random sequence generators all by themselves, but they have some annoying nonrandom properties. Sequential bits are linear, which makes them a poor candidate for encryption.
And large random numbers generated from sequential bits of this sequence are highly correlated and, for certain types of applications, not very random at all.

You might get a beautiful random sequence, but unless you saved every bit of that sequence there's no way to reproduce the simulation. Unix random Unix random is an example of a linear-feedback shift register RNG. According to Hash Collision Probabilitiesthe probability of all random numbers being unique is just: As such, we can combine it with other one-to-one functions, such as addition and XOR, to achieve a much better permutation. OpenBSD was sufficiently dissatisfied with it that they replaced it with a generator based on the ChaCha20 stream cipher.
