    Abstract:In this work, we prove the NP-completeness of two
    variants of tokenisation, defined as the problem of compressing a
    dataset to at most $\delta$ symbols by either finding a
    vocabulary directly (direct tokenisation), or selecting a
    sequence of merge operations (bottom-up tokenisation).
