i am loking a bit into this whole random thing and i am asking myself how the Random (Value) node generates its numbers?
Looking into the “about” nodesection on the vvvv-site does not offer me any information. It seems to be broken on the Random node^^ https://vvvv.org/documentation/random-(value)
Does anyone have a clue.

glad that finally someone asked the question to my answer from 2008:
ha! how could i not find that with google^^
so that pseudorandom it is.
i had a feeling ;) especially when i see the pricing of those real random number generating cards!!!
but could you tell me which kind of random function the node is using?
Random number generators are important in many kinds of technical applications, including physics, engineering or mathematical computer studies (e.g., Monte Carlo simulations), cryptography and gambling (on game servers).
This list includes many common types, regardless of quality.
Whenever using a pseudorandom number generator, keep in mind John von Neumann's dictum "Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin."
The following algorithm...
i have been looking some videos and they always state that most of the functions need a “seed” and sometimes more the more complex the random function is.

it’s a normal LCG, the algorithm most libraries use. details are listed here, look for borland delphi:
A linear congruential generator (LCG) is an algorithm that yields a sequence of pseudo-randomized numbers calculated with a discontinuous piecewise linear equation. The method represents one of the oldest and best-known pseudorandom number generator algorithms. The theory behind them is relatively easy to understand, and they are easily implemented and fast, especially on computer hardware which can provide modulo arithmetic by storage-bit truncation.
The generator is defined by recurrence relat...
