Determining the Impact Regions of Competing Options in Preference Space

Summary: Introduces k-Shortlist Preference Region (kSPR) to identify regions in the d-dimensional preference space where a focal record ranks in the top-k under weighted-sum scoring. Proposes a computational-geometry, exact framework for efficient kSPR computation; benchmarks show up to three orders of magnitude speedup over a prior competitor built from earlier work.
