# Formalization of Multiway-Join Algorithms

 Title: Formalization of Multiway-Join Algorithms Author: Thibault Dardinier Submission date: 2019-09-16 Abstract: Worst-case optimal multiway-join algorithms are recent seminal achievement of the database community. These algorithms compute the natural join of multiple relational databases and improve in the worst case over traditional query plan optimizations of nested binary joins. In 2014, Ngo, Ré, and Rudra gave a unified presentation of different multi-way join algorithms. We formalized and proved correct their "Generic Join" algorithm and extended it to support negative joins.
