Frequently Asked Questions

What is the difference between a pseudorandom number generator and a true random number generator?

A pseudo-random number generator is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. Computer based random number generators are almost always pseudo-random number generators. Yet, the numbers generated by pseudo-random number generators are not truly random.

What are the different types of random number generators?

There are two types of random generators: TRNGs (true random number generators) and PRNGs (pseudo-random generators). TRNGs use entropy sources like weather, atmospheric noise, thermal noise, or radioactive decay to obtain pure randomness. PRNGs are random but start to repeat after a certain number of seeds.

What is the best random number generator?

If you need bullet-proof random-number generation, use the Boost stuff, or C++11. For beginners, this is sufficient. Absolutely a better solution is to use Boost random number generator it was written by people who actually understand the problems associated with random numbers.

How do you generate a random number?

Random numbers can be generated by the Visual Basic Rnd()function, that returns a floating-point value between 0.0 and 1.0. Multiplying the random numbers will specify a wider range. For example, a multiplier of 20 will create a random number between zero and 20.
