In 11 can the ball cross its own path?

No.


So this translates to - each half white and fully white cell needs to be visited exactly once?

The white cell can be crossed twice. The path should not overlap with itself.


I don’t get it, can the road cross itself or not? Because your first answer is “No”, and the second one is “Yes”. Did you mean that a horizontal road segment and a vertical road segment can cross on a fully white cell? Are we talking about the 2017 April’s Opti-Roll puzzle; the road act same in here about crossing?

Para - 2018-04-03 7:00 PM

For 10. Does minimum mean the amount of digits or the sum of their values?

For 11. Can you place a black triangle in a given cell with a triangle to turn it into a fully black cell?

10. Minimize the sum by using fewer digits.

11. Yes.


Questions for 11:
Could one also place two triangles in an entirely white cell, turning it entirely black?
And if so, would you name the two trinagles as A and D or as B and ?

Also, in what order are the tringales to be given in the solution code? If it's in order of the path (as the example seems to imply) then where/how would one put in the triangles creating a full black cell, as the path doesn't visit them ?

I'd like to know when this test will end.
PB mentions "not later than 24-00 (of Moscow time) April 11 2018", but the timer in the submission page indicates 24 hours before that.

I understand the question as it is translated the translator. If the issue was not the word "own", I understood it clearly. The path can intersect itself (the fully white cell can be crossed twice), but the path should not overlap with itself.

It's possible. The order in the solution code is arbitrary.

For 11:
It's possible N=0?
Then a route with lenght=2 and N=0, i.e., is better that other with lenght= 40 and N=1?

A route must pass through all the white cells and half cells. If N=0, then the length of route cannot be 2 (this is much less than the number of white cells and white half-cells in the picture).

Fixed the end time. It should show correct time now.

Oh dear, I didn't see this contest was happening. Is there a mailing list to announce contests I could join?
Congratulations to the winners!
