By all accounts the shuffle on your mp3 player is actually random. Which
makes sense when you think about it, a Random Number Generator (or
Pseudo RNG for the pedants out there) is almost certainly a lot chepaer
than something that has 'favourites'. Yet despite this people insist
that their iPods or whatever have an agenda:
Probably because the Human Brain is one massive pattern matching machine
and true randomness has, well, patterns. Randomly.
But I was wondering if anybody knew of any papers out there for
deliberately non-random sequence generators - that conciously attempt to
not have any patterns.
A naive attempt would just make the probablity of a given track
appearing be a probability function of the number of items on the list
and the last time it was played.
A cleverer attempt might have a a numbe rof different fields for each
track and would try and make sure that it tried never play anything
with the same value in the same field next to each other.
I can't be the first to think of stuff liek this but my maths paper
finding fu is weak.
