The character of a sequence of apparently random numbers created by using some specific rules.
Such a constructed randomness is of course not really random. As already observed by J.von NEUMANN, it is possible to generate an apparently perfectly random series of numbers in a completely deterministic way… which is exactly the contrary of randomness, even if it is possible to introduce an “asymptotic decrease toward 0 of the self-correlation function of the numbers in the series”, as expressed by S. DINER (1992, p.350). As this implies a kind of “loss of memory” of the initial conditions (Ibid) the relation with chaotic dynamics is evident.
