最近货车den Broeck等人证明了二元逻辑FO 2语句的对称加权一阶模型计数问题(WFOMC)是多项式时间的,而对于某些FO 3-语句是#P1-完全的.我们在两个独立的方向上扩展了FO 2的结果:到形式为φ <$$> x <$$>=1 y <$$>(x,y)的句子,其中φ和<$在FO 2中公式化,以及到FO的一致一维片段U1的句子,FO是最近引入的二元逻辑的扩展,具有处理所有关系符号的能力。我们注意到,前者用函数关系符号推广了FO 2的扩展。我们还确定了一个完整的分类的一阶前缀类根据WFOMC是否在多项式时间或#P1-完成。
It was recently shown by van den Broeck at al. that the symmetric weighted first-order model counting problem (WFOMC) for sentences of two-variable logic FO2 is in polynomial time, while it is #P1-complete for some FO3-sentences. We extend the result for FO2 in two independent directions: to sentences of the form φ∧∀x∃=1 y ψ (x, y) with φ and ψ formulated in FO2 and to sentences of the uniform one-dimensional fragment U1 of FO, a recently introduced extension of two-variable logic with the capacity to deal with relation symbols of all arities. We note that the former generalizes the extension of FO2 with a functional relation symbol. We also identify a complete classification of first-order prefix classes according to whether WFOMC is in polynomial time or #P1-complete.
