You don't have all the players participate, just the top players.

Suppose you have 12 entries in a contest.  They play 24 games (12 each
white/black) using a round-robin format.  This will determine an approximate ELO
for the pool.  Then, for the top 4 players, have a swiss tournament of several
rounds.

The goal I would like to reach is a fair tournament.  In such a tournament, the
best program has a good chance of winning.  The separation between top programs
is very small.  In order to find out which one is really the best, careful
design of the tournament is needed.  Two or three rounds of a swiss tournament
with programs of unknown strength is little more than a crap-shoot.

On the other hand, the programmers are reluctant to play a lot of games.  So
perhaps having a 3rd or 4th place program win does not really matter.  It's
still a neat title to hang on the wall and it gives the underdogs a fighting
chance to win.
