The "computer program" solution was exactly what was used in the London
Mayoral election last time around.

All the ballot papers were scanned (which took hours longer than it had
been expected to) and then a computer system worked out the combinations
of first and second choices before declaring Boris the winner.

The flaw of the whole system is its closed nature; I was there as an
election observer with the Open Rights Group and our main concern was
that no one had a clue what the computer was doing and whether the
result was correct. The views of the group ranged from the sane "it is
probably accurate, honest and right, but we don't know this for certain"
to the rather over the top "it's clearly a fiddle and a massive
conspiracy"! To be fair, though, the election committee did have three
independent individuals who were given all the raw data and allowed to
create their own algorithms to check the result.

One of the interesting points of the day was speaking to the Election
Commission observer who was an Australian (where they use a similar
transferable vote system, but count by hand). She declared that the
computers were pointless and, had this been an election in Oz, they
would have finished the count hours earlier and been in the bar for five
hours already by the time we get the result!

Ultimately, though, we never found out what the in-built flow charts and
algorithms were - possibly because this information is commercially
sensitive for the private business that ran the computers and scanners.
