  1. A space efficient implementation of Crochemore's repetitions algorithm in C
  2. 2-factorizations of K9
  3. 2-factorizations of K11 (corrected)
  4. 192 known KTS(21)
  5. 2-factorizations of K13
  6. Run-maximal strings for lengths 2 to 35, a complete enumeration (only lexicographically smallest strings are listed,
    i.e. the inverted strings are not listed), all the runs are listed as well. These result were obtained independently of
    the alphabet; the fact that for bigger N's  they are all binary strings is of some interest as it supports a stronger
    hypothesis than that for every N, there is a binary string that admits the maximum number of runs.
  7. A program to compute maximal repetitions, runs, and distinct squares in a string based on Crochemore's
    portioning algorithm, implemented in C++ by Franek, Jiang, and Weng
    complete final version with memory saving techniques: crochB7.cpp and auxil.h
    original version without memory saving tachniques: crochB.cpp
  8. Erdos' conjecture on multiplicities of compete subgraphs - Jessie Liu's webpage, a Ph.D. candidate I supervise
  9. Maximum-number-of-distinct squares conjecture, (d,n-d) table - Mei Jiang's webpage, a Ph.D. candidate I supervise
  10. Maximum-number-of-runs conjecture, (d,n-d) table - Andrew Baker's webpage, a Ph.D. candidate I supervise
  11. R-cover and structure of run-maximal strings, a C++ program to generate candidates for run-maximal strings using the R-cover property: rcover.cpp, crochB7.hpp, auxil.h
    Generating candidates for run-maximal binary strings of length 35, the following sets were generated in 19 minutes (Gd is the set containing the candidates of length d):
    G4, G5, G6, G7, G8, G9, G10, G11, G12, G13, G14, G15, G16, G17, G18, G19, G20, G21, G22, G23, G24, G25, G26, G27, G28, G29, G30, G31, G32, G33, G34 and G35
  12. C/C++ linear implementation of runs algorithm by C. Weng - Chia-Chun (Jasper) Weng's webpage, an M.Sc. candidate I supervise
  13. C++ source code ub.cpp for computing a sorted Lyndon array from a partially sorted Lyndon array, see F. Franek, A. Paracha, and W.F. Smyth: The Linear Equivalence of the Suffix Array and the Partially Sorted Lyndon Array, AdvOL Technical report 2017/03
