论文摘要
词典组合物是从组件选择功能构建总体选择函数的自然方法。顾名思义，将组件排序并顺序选择。后续组件选择的集合受到早期选择功能做出的选择的约束。特定的约束影响是否保留了路径独立之类的属性。对于输入的几个领域，我们表征了确保这种保存的约束。
Lexicographic composition is a natural way to build an aggregate choice function from component choice functions. As the name suggests, the components are ordered and choose sequentially. The sets that subsequent components select from are constrained by the choices made by earlier choice functions. The specific constraints affect whether properties like path independence are preserved. For several domains of inputs, we characterize the constraints that ensure such preservation.
