New data structure offers faster suffix array queries

By PulseAugur Editorial · [1 sources] ·

A new research paper introduces a novel data structure for suffix array and inverse suffix array queries. This structure allows for queries on a text of length n to be answered in approximately O(tau^3) time, utilizing O(n/tau) words of auxiliary space for any tau value between 1 and n. The paper, authored by Sharma V. Thankachan, was submitted to arXiv on October 26, 2026, and is associated with various platforms like Hugging Face and DagsHub for code and data sharing. AI

    Tiny Suffix Arrays

    Suffix array and inverse suffix array queries on a text of length $n$ can be answered in $\widetilde{O}(τ^3)$ time using an auxiliary data structure occupying $O(n/τ)$ words, for any $τ\in [1,n]$.
