Landvermessung

(Published on 26. June 2019, 20:26 by Zzzyxas)

Schwärze einige Felder des Diagramms, sodass es von jedem schwarzen Feld zu jedem anderen schwarzen Feld höchstens einen Pfad entlang schwarzer Felder gibt, wobei dieser Pfad nur horizontal und vertikal zwischen benachbarten schwarzen Feldern verlaufen kann. Es darf also keine Kreise auf geschwärzten Feldern geben. Die Zahlen geben dabei an, wie lang der kürzeste Pfad ist, der alle Schwarzfelder unter den vier berührten Feldern benutzt. Dabei werden Anfangs- und Endfeld des Pfades mitgezählt. Ein Unendlich-Zeichen ∞ bedeutet, dass es keinen solchen Pfad gibt.

Solution code: Für jede Zeile von oben nach unten die Länge der längsten Folge von Schwarzfeldern.

Finally figured this one out. I see I asked a question a long time ago but unfortunately the puzzle got lost or discarded at some point...now perhaps I can try the advent 2020 puzzle

Maybe the English instruction here might help as well: https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?chlang=en&id=00030M

@ibag thanks for your explanation to bob which allow me to understand the rules too. If I understand properly, 2 means there are 2 adjacent black cells in the 4 cells around the number. 1 means 1 of 4 is black. 3 means there are 3. And the other numbers means there are 2 non adjacent black cells, linked by a way of the number indicated of contiguous black cells. Infinity symbol means 2 non adjacent black cells which are not linked.
I'll try it to verify...

Hier hab ich etwas länger gebraucht, bis ich die Regeln verstanden habe. Dann war es wirklich schön

Diese Rätselart hat echt Potential, finde ich

@ibag: Thank you very much. My German knowledge is getting better (and I have learned a LOT from the portal and the comments) but I mis-translated the first sentence, which seemed to imply that the black squares were all connected to make paths.

@bob: It's not a coral, because it's not necessarily connected. The infinity symbol means there are two fields around the symbol which are not connected at all. For an example look here https://logic-masters.de/LM/2019/raetsel.php in the instruction for the contest, round 4 puzzles 4.10 and 4.11.

So the black squares form a standard coral with no 2x2 areas (since that would create multiple paths)? And no black squares can go next to the infinity symbols (since even one black square is a path)? I am finding this puzzle completely unsolvable and am not sure if I understand the rules correctly. I can't find any other examples.
