The Complexity of the Homomorphism Problem for Boolean structures
arXiv - CS - Computational Complexity Pub Date : 2020-10-10 , DOI: arxiv-2010.04958
Libor Barto and William DeMeo and Antoine Mottet

We show that for a fixed Boolean structure $\mathscr B$ of arbitrary finite signature---i.e., not necessarily purely relational---the problem of deciding whether there exists a homomorphism to $\mathscr B$ is either in P or NP-complete.

布尔结构同态问题的复杂性

我们表明,对于任意有限签名的固定布尔结构 $\mathscr B$---即不一定是纯关系的---决定是否存在 $\mathscr B$ 同态的问题是在 P 或 NP 中-完全的。
