```There is something wierd with your message that the post sizes are quite large.

This is causing them (and my reply) to be auto moderated. Also, it shifted your
original post to my spam folder, which means that others may not have read it.

Anyway, hopefully this post wouldn't be that large as I have deleted everything
(unless the problem is with the header).

Right

Asset is actually alot less rigid. If there were 5 seats, there might
be 20-30 candidates and they would all have to negotiate what the
results would be. This allows each voter to know the person
they vote for.

In effect, you are picking someone to negotiate
on your behalf rather than directly picking a candidate. (Though
with the rules I suggested, the negotiations are constrained. In
ideal asset voting, the seats could be decided in any manner that
they candidates decides as long as they have enough votes)

If you are doing it on computer than then normal method is to
have each ballot stored along with a weighting.

The weighting is set to 1.0 at the start for everyone.

VC = Vote for the candidate
Quota = (Total Votes)/(Seats + 1)

1) Allocate each ballot to the highest ranked candidate
on the ballot who hasn't been elected or eliminated yet

2) Sum the weighting of all ballots for each candidate

3) If the highest candidate has greater (not equal) than the quots
-- The candidate is elected
-- Multiply the weightings of each ballots allocated to that candidate
by

(VC-Quota)/(VC)

Otherwise,

eliminate the candidate with the fewest votes

4) Goto 1) until all seats are filled.

There are some benefits from recalculating the quota as the
election progresses due to exhausted ballots. However,
that is not likely to be a problem for a student election.

Step 3 can be accomplished by randomly selecting ballots to
make up the surplus, but if you are using a computer anyway,
then that is not a problem.
