randfolge

randfolge is a term that typically refers to a sequence of random numbers. This sequence can be generated by various algorithms or physical processes designed to produce unpredictable outcomes. The properties of a randfolge are crucial for its applications, with the most important being unpredictability and uniformity. Unpredictability means that no part of the sequence can be reliably guessed from the preceding parts. Uniformity suggests that the numbers in the sequence are distributed evenly across the possible range of values.

There are two main categories of randfolge generation: pseudorandom and true random. Pseudorandom number generators (PRNGs) use deterministic algorithms to produce sequences that appear random but are ultimately predictable if the starting point, known as the seed, is known. These are widely used in simulations, gaming, and cryptography when perfect randomness is not strictly required. True random number generators (TRNGs), on the other hand, rely on unpredictable physical phenomena, such as atmospheric noise, radioactive decay, or thermal noise, to generate sequences that are inherently random. TRNGs are preferred for applications where high security and unpredictability are paramount, like generating cryptographic keys. The quality and statistical properties of a randfolge are often assessed using various randomness tests.
