CG Tournaments with Missing Games

Now, eliminate identifiable complete Round Robins, complete multiple-round Round Robins, and one-on-one player Matches and you have either Knockouts, Swiss, Round Robins with missing rounds, or “other”.

Here is such a list, where the tournaments appear to have fewer games than expected (but not too few, say within 10 games):

for t in iX:
   if t in RR or t in RRn or t in MG: continue
   (np,ng) = n_players(t,rr=1)
   if abs( ng - len(TG[t]) ) > 10 or ng==1: continue
   if n_players > 2: 
      nG = len( TG[t] )
      if nG > ng: continue
      print "%8d  %3d  %4d  (%4d %4d )    %s" \
         % ( t, np, nG, ng, (nG-ng), TN[t] )

We could also have listed the tournaments with more games expected. Some of these would be RR’s, where a tie-break playoff was mixed in. These would be candidate tournaments for screening, since we (well, at least me) would want to separate out the playoffs:


>>> for t in iX:
       if t in RR or t in RRn or t in MG: continue
       (np,ng) = n_players(t,rr=1)
       if abs( ng - len(TG[t]) ) > 10 or ng==1: continue
       if n_players > 2:
          nG = len( TG[t] )
          if ng > nG: continue
          print "%8d  %3d  %4d  (%4d %4d )    %s" \
             % ( t, np, nG, ng, (nG-ng), TN[t] )
