Abstract Minimal model and partial implication semantics play important roles in the subfields of artificial intelligence. In this paper, the complexity issues of minimal model and partial implication semantics are analyzed when the antecedent and the consequent are literals, literal sets and formulas respectively. The results show that the complexities of minimal model and partial implication semantics increase when the antecedent and consequent become more complex. Moreover, the complexities of all these decision problems lie in the first two layers of polynomial hierarchy.
