- Title:
- Computational Complexity of NURIKABE
- Abstract:
- We show that the popular pencil puzzle NURIKABE is intractable from the computational complexity point of view, that is, it is NP-complete, even when the involved numbers are 1 and 2 only. To this end, we show how to simulate Boolean gates by the puzzle under consideration. Moreover, we also study some NURIKABE variants, which remain NP-complete, too.
