论文摘要

通过功能符号的约束的满意度,我们考虑了非阴性整数的数值不平等。我们认为的约束是线性系统AX = B的连接,以及形式X_I> = x_j^n(x_i <= x_j^n)的(非)凸约约束的连词。我们表明,即使对线性部分的解决方案明确给出了这些约束的满足性,即使对线性部分的解决方案也是NP库。结果,我们获得了NP完整性,以扩展具有功能图像S = F [p^n]的基集(QFBAPA)的某些无量词约束。

Motivated by satisfiability of constraints with function symbols, we consider numerical inequalities on non-negative integers. The constraints we consider are a conjunction of a linear system Ax = b and a conjunction of (non-)convex constraints of the form x_i >= x_j^n (x_i <= x_j^n). We show that the satisfiability of these constraints is NP-complete even if the solution to the linear part is given explicitly. As a consequence, we obtain NP completeness for an extension of certain quantifier-free constraints on sets with cardinalities (QFBAPA) with function images S = f[P^n].
