- All or nearly all the discussion on RNG's in this group deals with
- algorithmic generators, and one of the conclusions one might reach is
- that they are all flawed in one way or another. Some of the confusion
- arises from the variety of criteria for adequacy, or the variety of
- applications among those interested in RNG's. Presumably if it were
- possible to create an algorithm that could generate "truly" random
- numbers, there could be a GAA. This brings me to my question:
-
- Why don't people interested in "good" RNG's simply use one or another of
- the physical random sources, such as radioactive decay or quantum tunneling.
- Obviously these would not be appropriate for cases where a repetition of
- the random sequence is desired, but otherwise...? For a couple of
- thousand dollars, which is a trivial cost compared to the time spent on
- algorithmic RNG research, one can buy excellent, well designed and
- executed commercial RNG's. I would be interested in some discussion of
- problems or inadequacies (or indeed virtues) of so-called "true" random
- event generators.
