同构蕴涵

Isomorphic Implication

Michael Bauland, Edith Hemaspaandra

摘要:

研究了布尔约束的同构蕴涵问题。我们表明,这是一个自然的模拟子图同构问题。我们证明,根据一组约束,这个问题是在P,NP-完全,或NP-硬,coNP-硬,并在并行访问NP。我们将展示如何扩展NP-硬度和coNP-硬度硬度的并行访问NP的某些情况下,并推测,这可以在所有情况下完成。

英文摘要:

We study the isomorphic implication problem for Boolean constraints. We show that this is a natural analog of the subgraph isomorphism problem. We prove that, depending on the set of constraints, this problem is in P, NP-complete, or NP-hard, coNP-hard, and in parallel access to NP. We show how to extend the NP-hardness and coNP-hardness to hardness for parallel access to NP for some cases, and conjecture that this can be done in all cases.
