On this page you can choose your favourite problem of each cycle.
In February, 2003, first such vote took part.
You can see the current leaders.
And, because more people said it was quite interesting, I have decided to leave this possibility
also later on (without any deadline). If some of the leader will be changed, it will be shown
on these pages.
You can vote on your favourite problem below, just put the number of your favourite problem at any of
the 12 CYCLONE themes shown in the book.
You can write only one problem in the cell (or leave the cell empty).
