Random number generators have changed the game when it comes to ensuring fairness and true randomness when randomness is needed. There are many uses for random number generators, which we’ll explore in this article, as well as how they actually work because we’re not sure this is properly understood.
How Random Number Generators Are Used
If you want to know how and where random number generators are used, we’ll tell you everything you need to know. Whether it’s online lotteries, video game development, or even science laboratories, there are many different uses.
Online Lotteries
If you’re a fan of lotteries, such as the Lottoland online lottery, then we’re sure that you’ll have heard of random number generators and understand why they’re absolutely essential. Whether you play the Irish Lotto, the Millionaire Lotto, or the Powerball, all these online lorries rely on random number generators to be genuinely fair and reputable. If you know a draw is truly random, you’re more likely to enter and play along.
Video Game Development
With modern video games becoming increasingly sophisticated, there is an additional need for dialogue and non-playable characters to be more human-like. While this may seem simple, this relies on multiple decisions needing to be made at any time, which is when random number generators come in useful, providing seamless interactions between the player and the other in-game characters.
Science Laboratories
When things are tested in lab conditions, the number of different variables needs to be tested randomly and without human interference, which is why random number generators are so helpful. In double-blind trials, not even the lead researcher can know which sample is which, so having a number randomly assigned helps to ensure that no bias can be applied to the research, even if it isn’t deliberate.
How Random Number Generators Work
In today’s age, random numbers are often assigned using a random number generator, making it easier and more accessible than ever before. This is often done with either a hardware device, like a calculator-like handheld machine, or a software algorithm, usually accessed via a website or application. This random number is taken from a limited or unlimited set of digits, deciding on the user’s preferences.
There are generally two types of random number generators, known as pseudorandom number generators and true random number generators.
Pseudorandom Number Generator
A pseudorandom number generator is software-based and uses surprisingly sophisticated algorithms to mimic the true randomness of random numbers being selected. While these are random in most cases, they can’t be genuinely random as the algorithm is based on distribution, meaning it’ll follow set rules and operate predictably, allowing for manipulation.
True Random Number Generators
A true random number generator, also known as a hardware random number generator, does not use an algorithm, instead using a physical variable to generate random numbers. These pieces of technology are extremely advanced, typically using unpredictable variables such as radioactive decay to produce truly random results. These machines are the best way to produce true randomness but aren’t as accessible to members of the public.
