WSPC Organizer Posts: 701 Location: India | devarajand - 2012-05-07 7:46 AM Can one take a break between part A and B It does not say you have to take both parts together and 'independent parts' surely implies that you can take as long a break in between as you like. Also, I'm sure you can participate in Part B before Part A if you wish, there doesn't seem to be any restriction. | ||

And you are allowed to start part B before part A. | ||

Isn't it simply an 'Odd-Even View Sudoku'? No. The example has multiple solutions as an 'Odd-Even View Sudoku' (We can swap 5 and 6 in Column 2/3). | ||

WSPC Organizer Posts: 701 Location: India | The total points is 808 and time is 128 minutes. That means, a player who finishes all puzzles within the time limit is solving at the speed of at least 6-7 (and maybe more) points per minute, whereas the time bonus is just 3 points per minute. I think the time bonus should be increased. In particular, players completing Part A and Part B would be solving at a speed greater than 5.5 points per minute and 7 points per minute respectively. The time bonus of 3 points per minute looks meager and will surely not give a good indication of the different of performances of players who complete the test before time. Obvious Issue: Players completing Part B should be given a higher time bonus than those completing Part A. | ||

No. The example has multiple solutions as an 'Odd-Even View Sudoku' (We can swap 5 and 6 in Column 2/3). There is a difference between OEVS and OEVSS. If you have in one row numbers "213..." the first visible odd skyscraper is 3, because 1 is covered by 2. | ||

If you have in one row numbers "213..." the first visible odd skyscraper is 3, because 1 is covered by 2. Ok. I get it. The example doesn't have any such case, so it was misleading. Thanks. It did have a few examples I think, not exactly like the 213, but skyscraper logic was required. The "2" below R6C5 had to be satisfied in the first cell itself, since the 5 would block vision towards the 2. This is not the case in Even Odd View I guess, you could've had 5 in the first cell and 2 in the next with the "2" outside clue. (I'm saying this with memory of solving yesterday, so the placements may be a bit off, but the logic was there) | ||

Are there any restrictions for regions with exactly 8 cells? In the competition, there will be no regions with 8 cells. In the IB, you should aply both rules at once - in region with 6 cells no digits may repeat and each digit should appear at least once. | ||
