Abstract

The Method of Equal Shares (ES) is a popular approval-based multi-winner voting rule, which was originally proposed by Peters and Skowron. It satisfies several well-known representation axioms, like extended justified representation (EJR) and priceability, and it can be computed in polynomial time. Further, it has already been employed in several real participatory budgeting elections. In this note, we prove that ES is an instance of the EJR-Exact family of voting rules that also satisfy EJR and were proposed by Aziz et al. 2018 before the work of Peters and Skowron.

关于平分法的说明

平等份额法（ES）是一种流行的基于批准的多赢家投票规则，最初由Peters和Skowron提出。它满足几个众所周知的表示公理，如扩展正当表示（EJR）和可定价性，并且可以在多项式时间内计算。此外，它已被用于几次真正的参与性预算编制选举。在本文中，我们证明ES是EJR- exact投票规则家族的一个实例，它也满足EJR，由Aziz等人于2018年在Peters和Skowron的工作之前提出。

期刊介绍： Information Processing Letters invites submission of original research articles that focus on fundamental aspects of information processing and computing. This naturally includes work in the broadly understood field of theoretical computer science; although papers in all areas of scientific inquiry will be given consideration, provided that they describe research contributions credibly motivated by applications to computing and involve rigorous methodology. High quality experimental papers that address topics of sufficiently broad interest may also be considered. Since its inception in 1971, Information Processing Letters has served as a forum for timely dissemination of short, concise and focused research contributions. Continuing with this tradition, and to expedite the reviewing process, manuscripts are generally limited in length to nine pages when they appear in print.
