Yin-Yang Puzzles are NP-complete [article]

Erik D. Demaine, Jayson Lynch, Mikhail Rudoy, Yushi Uno
2021 arXiv   pre-print
We prove NP-completeness of Yin-Yang / Shiromaru-Kuromaru pencil-and-paper puzzles. Viewed as a graph partitioning problem, we prove NP-completeness of partitioning a rectangular grid graph into two induced trees (normal Yin-Yang), or into two induced connected subgraphs (Yin-Yang without 2 × 2 rule), subject to some vertices being pre-assigned to a specific tree/subgraph.

Without preventive measures to supplement the iron with animals, up to 100% of piglets become sick with anemia, which can lead to the death of a significant part of the young population. This article presents the results of the toxicological approbation of a new iron-containing preparation for farm animals. The question of finding a less toxic iron preparation with a higher prolonging effect is relevant.
