arXiv:2602.05448v4 Announce Type: replace Abstract: Selecting the top $m$ from $n$ items via expensive $k$-wise comparisons is central to settings ranging from LLM-based document reranking to crowdsourced evaluation and tournament design. Existing methods either rely on heuristics that discard comparison information, or exploit it at prohibitive cost. We introduce a tournament graph framework that provides a principled foundation for $k$-wise ranking. Our key observation is that each $k$-item comparison reveals an induced tournament of $\binom{k}{2}$ pairwise preferences; aggregating these int
The proliferation of LLMs and the increasing need for efficient, scalable ranking systems across diverse applications necessitate more principled and less heuristic-driven approaches to comparison and selection.
Improving the efficiency and accuracy of ranking systems, especially for LLM outputs and large datasets, directly impacts decision-making, content delivery, and the utility of AI systems, providing a significant competitive advantage.
This research introduces a robust, principled framework for k-wise ranking that reduces computational cost and reliance on heuristics, potentially leading to more effective and scalable AI applications.
