Compact Representation for Matrices of Bounded Twin-Width

pdf-format:
LIPIcs-STACS-2022-52.pdf (0.7 MB)


Abstract

For every fixed d ∈ ℕ, we design a data structure that represents a binary n × n matrix that is d-twin-ordered. The data structure occupies 𝒪_d(n) bits, which is the least one could hope for, and can be queried for entries of the matrix in time 𝒪_d(log log n) per query.
