If they move horizontally "and" vertically that basically results in a possible diagonal movement.

In puzzle 2 (Crossroads), in the description is "the line passing through this strip" the straight line segment between the two turns (one for each side of the strip), or the whole line between the two adjacent strips?

I have a question about the 3rd Optimizer (the Football one). It is said that a ball cannot cross a circle of the opposite color. But is it possible for the ball to cross a circle of the same color (like if we consider that this player has already got the ball once)?

No, in this case, the ball is re-addressed to the player who cannot be used.

For Record Score, does the goal shot also count as part of the path? Especially, if one team has a player next to the opposite goalkeeper, can the same order of players count twice (since this player can kick the ball directly or diagonally into the goal) or is this counted as the same path?

I have some clarifications for the optimizers. Please correct me if I'm wrong.

10. Opti-Road:
There is an error with the example. The column digits should be 22212, not 21212.
Also there is an error with the example answer key: the score for the example is 8, not 9.

11. From 0 to 9:
Without parentheses, we will always do multiplication and division (x and /) before addition and subtraction (_PLUS_ and -). Also, dividing by 0 is not allowed.

12. Record Score:
Total score is number of white paths plus number of black paths. The example is simple so I attach another one.
In this, White has 1 path, 1235674 (this is from the previous question from Christian - I think it is not important which direction #4 scores?).
And Black has 2x2=4 paths, 1234567, 1234576, 1324567, 1324576. It is not possible to go from #4 to #6 directly.
And so the total score for this example is 5.

What about CJK's question:

Is it allowed to use programs or similar things, especially for the optimization puzzles?

Of course, programming is usually not allowed in puzzle contests -- but ususally there are no optimization puzzles and especially for No. 11 it is obviously quite tempting to do some... ;)

Thanks James:
10. You're right, I'll correct the example and the meaning of the expression in the answer format.
11. Yes.
12. Yes.

Hello,

For optimizer 11, is 2_PLUS_3=5 an equality, or must there be an arithmetic sign on both sides of the equality sign = ?

Hi Stefano,
1. It is not forbidden, but the fragments do not overlap each other.
2. Yes.

Hi, what about -2*-4=8? it would give more points but i guess it could also be forbidden since in that case the "-" sign is not really used as an operator

Hello,
If I am not mistaken, CJK's question doesn't have an answer yet. It would be convenient to know if we have to work only with paper/pencil for the optimization problems or not, in order to be rated with the same criteria.
Thank you very much!

The intermediate result can be fractional, but it is forbidden to construct numbers using a dot or comma.
