In the scope of my research, I wrote the following open source software.

C++ Libraries & Frameworks:

  • iopp: I/O utilities (File processing with iterators, bitwise I/O, memory mapping, etc.)
  • pm: Interface and utilities for performance measuring (running time, memory allocations, etc.)
  • random-permutation: Online generation of random permutations
  • word-packing: Word packing of integer sequences
  • tudocomp: Framework for the development of compression algorithms (outdated)

Experiments:

  • distwt: Distributed Wavelet Tree and Matrix Construction (Master's thesis and publication at ALENEX 2020)
  • sea21-predecessor: Engineering Predecessor Data Structures for Dynamic Integer Sets (Publication at SEA 2021)

For internal presentations, I have created slides on selected articles:
