I made a judgment. How come I don't see it?


Paz, I see that you gave the quality marks for all problems but you didn't make their order (at least first 12). If you already had the order, please send it in a note to Administrator. Anyway, thank you for interesting comments which will certainly be quoted in the next issue of Mat Plus.

How the points were calculated?

For example,

#1887 has got 12th and 8th places and 19 points.

#1897 has got 6th and 10th places and only 16 points.

Thank you Georgy for keeping the eyes wide open! I made a bug calculating the average for problems by judges. It is fixed now and the new list has just been uploaded (the same link as before: http://www.milanvel.net/pub/lp09_03.html).

 QUOTE 
How the points were calculated?

The places are first converted to points according to the LP rules (25,20,16,13,11,10...) and then summed. The judges get additional points in their lists for their own problems, if any. Thus the calculation for two problems mentioned by Georgy is:
1887 (12th and 8th place + average): 4 + 8 + 1(not 7!) = 13 points
1897 (6th and 10th place, not a judge): 10 + 6 = 16

You'll see that although the score for 5 problems by judges has changed the order remained the same except for the lowest ranked of 5.

Obviously a typing error, corrected in the previous post to 25,20,16...
