Back to business.

I tried to run the genetic seating generator with N=99. The thing is that above 75 players, the seating is done by taking the 50-players optimal seating, and adding the complementary N-50 seating. For instance, the 99-players seating is done with tables 1-10 matching the 50-players table, and tables 11-20 matching the 49-players seating.

It works, but it means that only half the tables truly have an optimal seating. By mixing all 99 players together, one can further smooth the irregularities and have a better seating.

I had to improve the genetic algorithm that would tend to give bad results on rules 5 and 7 because they had all-or-nothing scores. By refining the results (by giving a score matching the number of badly seated players), the algorithm works better.

Here's the seating for 99 players in the archon 1.5g

If you want to contribute or to play with the seatings, you just have to download and unzip www.vekn.net/images/stories/downloads/VtesSeatings.zip

There are two programs:

1) genetics.exe
This command-line program tries to find the best seating for a given number of players.
To use it, you have to run it through a command line with two parameters:
- the first one is the number of players (eg., 51)
- the second one is the size of the "population" that will breed and mutate to give the best results. Typical value is 1000.
The program will create a population for each of your logical processor. On my computer, it means 8*1000 individuals. If you have only 4 logical processors, you may want to double the population size. You can run the program in background since it has a very low priority and won't block your computer.



2/ RuleChecker.exe
You simply run it by double cliking on it. It always assume that the R1 seating is 1, 2, 3, ..., n so for 2R+F tournaments, you have to fill the first line only, and for 3R+F tournaments, two lines.
It can also import from your clipboard your seating if you copied it from the Archon file (by selecting the player numbers in the Optimal Seatings sheets) or from the Genetic program.
It will indicate if the rules are enforced or not.
