assistant: I did and you're right! However, you're not 100% right. REM out line
   2040 and see what happens. You'll find that it isn't the whole routine
   but only the code that does not allow a character to be swapped with
   itself. Logically that doesn't make any sense. In order for the routine
   to work well it must include the possibilty of exchanging a character
   with itself! I haven't studied it enough to see why it does what it
   does.  (If anyone knows the answer I would like to know!) I did however

assistant: Hmmm... Interesting! Of course, swapping a character with itself is a
"null operation", that does nothing. However, REMing out that line has
another effect, it prevents the generation of a new random number and
the swapping of the character with the one thereby specified. So,
whereas your original coding forced a "real " (i.e. non-null) swap to
occur, the modified coding permits the null operation.
Yes, I can see that this may improve your routine somewhat. However, I
still don't believe it will turn out to be truly random, giving equal
(long-term) frequencies to the generation of each of the six possible
permutations.
Think about this: In its modified form, your routine does three swaps,
each of which can have three outcomes (including the null one). So there
are 3^3, i.e. 27, different and equi-probable "routes" that can be taken
through a kind of decision tree. But there are only six different
possible outcomes. So several of the routes must lead to identical
outcomes. Okay. So far, so good. But it is impossible for 27 routes to
be equally divided among the six outcomes, since 6 is not an exact
factor of 27. Therefore some of the outcomes must be reached by more
routes than some of the others, and therefore be more probable.
If you think about it, my routine involves a decision tree with N! (N
factorial) branches, each of which leads to one of the N! outcomes. So
the outcomes are equally probable.
Anyway, I'll make the change (REMing that line) and also increase T to a
larger value, to show up smaller variations in frequency. I bet this
will show that your routine still produces different frequencies for the
outcomes!

Write your reply.

assistant: Later...
Did that. It turned out that the outcomes acb, bac and bca were each
about 25% more frequent than each of the other three. So I suppose these
more-frequent outcomes must each have five of the 27 branches of the
tree leading to them, giving each of them a 5/27 probabilty of
occurrence, while the other three each have four branches, and 4/27
probabilities. Of course, 3*5/27 + 3*4/27 comes to 27/27.

assistant: Well, I haven't tried it (though it looks very like a routine that
someone else posted in this thread way back near the beginning), but
I'll comment on it anyway!
It does ten swaps. For each swap, U can have any value from 1 to 3, with
each being equi-probable, and the same is true for S. So there are nine
different equi-probable decision-tree branches for each swap. Since
there are ten swaps, there are 9^10 (some very large number)
equi-probable branches at the end of the tree.
Going back to the logic of my last message, the question is: Can equal
numbers of these branches generate each of the six possible permutations
of three letters? In other words, is 6 an exact factor of 9^10 ? And the
answer to that question *must* be "no"! All powers of 9 must be odd
numbers, since 2 is not a factor of 9, but all multiples of 6 must be
even.
So I am certain that even this modified Fortune routine cannot produce
*exactly* equal probabilities of occurrence for the six permutations.
However, it may produce probabilities that are exceedingly close to
being equal. 9^10 is such a large number that there are is, for example,
extremely little difference between a probability of 123456/(9^10) and
one of 123457/(9^10). Theoretically, they are different, but it is
unlikely that any experiment of practicable length would show this
difference as a perceptible change of frequency.
So, yes, your modified routine is a lot better than  your previous one,
but it still isn't perfect. And it needs to do ten sets of calculations
and swaps. I still prefer my routine, which produces a theoretically
perfect result in just two swaps!
Don't you agree?!

assistant: Actually I was thinking of using the length of the string passed to
   determine the number of exchanges to make.
  That it may "produce probabilities that are exceedingly close" is good
  enough for me. I like the idea that it has that "randomness" built in!
   Yes but only when there are only 3 characters in the string. What
   happens when there are more characters in the string?
   Who me? I'm not known, nor have I ever been known for that type of

assistant: Hi!
I posted a 'false' solution some time ago, because I didn't know that you
all would make such a big problem out of randomness. Here my solution...
Record running water and mix it with tv noise. Then digitize this and use
it to scramble the characters like this... ;-)
RANDOMIZE TIMER
OPEN "WATER.RAW" FOR BINARY INPUT AS #1 ' the sample e.g. 500.000 bytes
FOR I=1 TO 25
  F=0
  WHILE F=0
    X=INT(RND*1000)+2
    GET$ 1,X,B$                         ' get 'random' number of bytes
    X=ASCII(RIGHT$(B$,1)) AND 3         ' make byte 0-3
    Y=ASCII(LEFT$(B$,1)) AND 3          '      "
    IF X>0 AND Y>0 AND X<>Y THEN        ' delete X<>Y if you want ;-)
       F=1
    END IF
  WEND
  Temp$=MID$(Text$,X,1)
  MID$(Text$,X,1)=MID$(Text$,Y,1)
  MID$(Text$,Y,1)=Temp$
NEXT I
CLOSE#1
END
Maybe this is random (I'm not a mathe wiz), but IF... it would be an
'overkill routine' just to scramble three characters! ;-)

assistant: ....
Well, sure, there are ways of generating random numbers that depend on
physical phenomena, rather than the mathematical algorithms that are
used by things like RND. Radioactive decays, which physicists believe
are *absolutely* random - i.e. incapable of exact prediction no matter
how much information is known about the physical situation -, are used
in some circumstances. And, yes, it would be possible to use these to
scramble the characters in a string, or anything similar.
Whether it's "overkill" depends on how important the results are. If
you just want to play games at home, it may not matter if some results
come up much more often than others. But if you're running a lottery,
with huge amounts of money at stake, you'd better be sure that there is
no non-randomness in your numbers, since if there is people could use it
to "break the bank" - i.e. put your organization into bankruptcy.
But...
The fact that you're generating your "random" numbers, X and Y, by some
physical method, instead of by using RND, does *not* evade the fact that
your calculations are *fundamentally* flawed, in the same way as Robert
Fortune's. You're doing 25 swaps, each of which depends on two "random"
numbers in the range 1 to 3. So the total number of branches in the
decision tree is 9^25. Since all powers of 9 are odd numbers, and all
multiples of 6 are even, there is no way in which equal numbers of
branches can go to each of the six possible permutations of three
characters. So the permutations must *not* be (exactly) equi-probable,
no matter how your "random" numbers are generated.
More like a red herring...

come in.
No, there is nothing wrong with your link.  ---- WYSIWYG ----.

Frequently reading the PowerBasic Compuserve Forum proves it. Have a look.
Bis dahn,
