RE: Random Iterations -
So what you want to do is like shuffling a deck of cards, but you only have 15 cards. The way I always handled that kind of thing was to make an array of the right length (N=15), initialize it with identity values (so array[1] = 1, array[2] = 2, etc). Then write a loop that goes from 1 to N. In the loop, generate a random number from 1 to N and swap the array value at the current loop index with the array value indexed by the random number. Each run through this loop is a "shuffle". To get a nice randomization, shuffle the deck seven times.

RE: Random Iterations -
Just 40 random ones ? Well that would be easier :-) The issue then is, how random? Random is relative, random for a bicycle lock or random to arm a nuke? ;-] WG > -Original Message- > From: Dobris, Eric [mailto:[EMAIL PROTECTED]] > Sent: 18 December 2002 17:58 > To: CF-Talk > Subject: RE: Random Iterations - > > > Yes, > I just need to be able to generate them and choose 40 random combinations. > I don't need to actually buld a table with > 1,307,674,368,000 rows. > > Eric > -Original Message- > From: webguy [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, December 18, 2002 12:37 PM > To: CF-Talk > Subject: RE: Random Iterations - > > > BTW you know there are > > 1,307,674,368,000 > > different non-ordered sets > > WG > > > -Original Message- > > From: webguy [mailto:[EMAIL PROTECTED]] > > Sent: 18 December 2002 17:15 > > To: CF-Talk > > Subject: RE: Random Iterations > > > > > > That requires a pretty intense algorithm, you going to be doing this > > often?

RE: Random Iterations
If I wanted to do this, I would look up combinatorics on Google. There are a lot of sites that have javascripts that do exactly this. It depends on how many items you have as to the processing power it would take to compute these.
