diff? Sorry, no.
I did it only on Business & Office Category, by hand. So run election for 1 seat, copy the winner. Add winner to the withdrawn list, run the election again.
I think it should give same results as frictional transfer, only we would have ranking.

I wanted to say the problem with frictional transfer, and not your script, was that it doesn't give ranking.
I'm trying to find a solution which would use the same algorithm only with ranking.

Your script uses fractional transfer?
In that case I'm sorry. I've lost track. You have my support.

I'm really sorry to ask... but if the "fractional transfer" from mmlado and neal does the same but in different ways... why are the results different?
There must be a small mistake in one of those algorithm... or have I overseen something?

We already have a mechanism to remove candidates, by saying they have withdrawn. It's even easier to run my proposal.

Both scripts generate a ranking, both are based on the STV used in the council election, but they are not necessarily equivalent (ie I cannot prove nor disprove it)
By construction, mmlado's method (which is the one I proposed some pages ago, but he has a working implementation) will give a consistent ranking.
Not sure about neals one (ie, can it produce {A}, {A,D}, {A,B,C} out of the A,B, C and D participants?) as far as I know it didn't happen, but I don't know if it can.

As I see it we both get the apps in list that would be returned by FTSTV if we run them for the appropriate number of seats, only the ranking is different. And that can be a big difference for the winners.

- Run election for one seat. This one will be the winner. (This step is common for neal's and mmlado's approach). In the example MeePasswords gets chosen and is selected as first.
- Next: run election for two seats. Now MeePasswords and LUCID iron get elected. MeePasswords was already chosen as first place so LUCID iron is chosen for second place.
- Next: run election for three seats. Now MeePasswords, LUCID iron, and ClipMan get elected. MeePasswords and LUCID iron had already been assigned to places 1 and 2 so ClipMan is chosen for place 3.
- etc.
mmlado's approach explicitly eliminates candidates for the next voting run by saying already chosen candidates have withdrawn. I don't know the mechanics/mathematics well enough but the different results are most probably caused by the remaining votes being distributed differently among the remaining candidates as compared to neal's approach.
