Abstract

For a given π=(π0,π1,...,πk){0,1,}k+1\pi=(\pi_0, \pi_1,..., \pi_k) \in \{0, 1, *\}^{k+1}, we want to determine whether an input kk-uniform hypergraph G=(V,E)G=(V, E) has a partition (V1,V2)(V_1, V_2) of the vertex set so that for all XVX \subseteq V of size kk, XEX \in E if πXV1=1\pi_{|X\cap V_1|}=1 and XEX \notin E if πXV1=0\pi_{|X\cap V_1|}=0. We prove that this problem is either polynomial-time solvable or NP-complete depending on π\pi when k=3k=3 or 44. We also extend this result into kk-uniform hypergraphs for k5k \geq 5.
