In one step specialization of current clause, to generate candidate constraints, BPU-CILP first projects the binding table of current clause to n-dimensional real space R〓(where n is the number of numerical attributes of the binding table), which produces some points labeled as positive and negative in R〓.

在对当前子句进行一步特殊化操作时，为导出候选约束，BPU-CILP首先把当前子句的绑定表投影到n维实数空间R〓（n为绑定表中数值属性的个数），得到R〓上若干标记为正/负的两类点。

The process includes a steps of using a matrix outer product structure of R to determine all of the unique entries in R and storing the unique monomials.

这个过程包括步骤：使用R的一个矩阵外积结构，确定R中所有的唯一项，并且保存这些唯一的单项式。
