Research Projects

Papers

  • On the Hardness of Smallest RLSLPs and Collage Systems Reviewed

    Akiyoshi Kawamoto, Tomohiro I, Dominik Köppl, Hideo Bannai

    Proc. DCC   243 - 252   2024.3

    　More details

    Language：English   Publishing type：Research paper (international conference proceedings)  

    We show that finding a smallest run-length compressed straight line programs (RLSLPs) is NP-hard for unbounded alphabet size. The same proof can be adapted for finding a smallest collage system. Additionally, we give a MAX-SAT encoding for computing a smallest RLSLP.

  • Extending the Parameterized Burrows–Wheeler Transform Reviewed

    Eric M. Osterkamp, Dominik Köppl

    Proc. DCC   143 - 152   2024.3

    　More details

    Language：English   Publishing type：Research paper (international conference proceedings)  

    We propose a generalized pattern matching combining parameterized with circular pattern matching. As an indexing data structure for such a matching, we enhance the parameterized Burrows--Wheeler transform (pBWT) of Kim and Cho with techniques derived from the extended Burrows--Wheeler transform of Mantaci et al., obtaining time and space complexities similar to the pBWT.

  • Computing LZ78-Derivates with Suffix Trees Reviewed

    Dominik Köppl

    Proc. DCC   133 - 142   2024.3

    　More details

    Language：English   Publishing type：Research paper (international conference proceedings)  

    We extend the LZ78 substring compression introduced in \cite{koppl21nonoverlapping} to the LZ78 derivates LZMW and LZ double. As a byproduct, we obtain the first linear-time algorithm for integer alphabets independent on the text compressibility.

  • Computing Longest Lyndon Subsequences and Longest Common Lyndon Subsequences Reviewed

    Hideo Bannai, Tomohiro I., Tomasz Kociumaka, Dominik Köppl, Simon J. Puglisi

    Algorithmica   2024.3( ISSN：1432-0541 )

    　More details

    Authorship：Corresponding author   Language：English   Publishing type：Research paper (scientific journal)  

    We improve on \cite{bannai22computing}, we could improve the time and space complexity of our online algorithm, where we shaved off a factor linear in the alphabet size
