Pairingalgorithm in Swiss System

Hi,

i'm working at a small programm to make an easier pairing for small tournaments.

 

In the offical Definition at Point c6 is written:
C6 Try to find the pairing
Pair the highest player of S1  against the highest one of S2, the    second highest one of S1 against  the second highest one of S2, etc. [...]

  • in case  of a homogeneous or remainder score bracket:  remaining players are moved down    to the next score bracket. With this  score bracket restart at C1.
  • [...]

 


If you have a look at C1 you can find:
C1 Incompatible player
If the score bracket contains a player for whom no opponent can be  found within this score bracket    without violating B1 (or B2, except  when pairing top scorers) then:

  • if this player was moved down from a higher score bracket apply C12.
  • if this score bracket is the lowest one apply C13.
  • in all other cases: move this player down to the next score bracket

I'm having problems to understand what happens between these both points. Additional at C6 "homogeneous group" is written about players, at C1 its only one player.

How are this points associated and what is to do? I used the source from here: fide Handbook and realy hope for Help. Many Thanks if there is someone out who's knowing!

Supposed I am in the first Pointgroup at c6 and not be able to make P paarings. Then I moved down the remaining players to the next score bracket and with the next Pointgroup resumed at C1.
right?

What's going on with this moved players?
"If the score bracket contains a player for whom no opponent can be found within this score bracket appy C12"

Is these for the second Pointgroup? What's to do? Will I have to check if it is possible to make Pairings like in c6 and will be lucky if it is possible?

I'm rooting for you, coder2 (don't you think I'm not). Smile

It's a vague article but actually it doesn't have to be important. You could check for players who cannot be paired against anyone. You could do a quick search to see if a pairing is possible at all. Or you could even just continue and arrive at C12 anyway in the end. At least that's my interpretation of the use of the article on imcompatible players
