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. |

There will absolutely be no restrictions between two parts. Breaks are allowed. And you are allowed to start part B before part A. |

No. The example has multiple solutions as an 'Odd-Even View Sudoku' (We can swap 5 and 6 in Column 2/3 ).

Country : India | vopani posted @ 2012-05-07 11:38 AM 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. |

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. |

Yes, we know about it. We will talk about it with Deb soon. The bonuses may be changed. |

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 ) |

I have one question about B6 (Surplus-deficit sudoku).
Are there any restrictions for regions with exactly 8 cells?
We will update the instructions - " In regions with less than or equal to 8 cells, the numbers should not repeat." |

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. |
