My papers: (with abstracts) (MathSciNet) (arXiv)

–6. (pdf) On successive sampling and fixed inclusion probabilities. Preprint, 2010.
  • Sampling.nb (pdf version): A Mathematica worksheet that goes through the calculations in the article; examples are also given.
8. (pdf) Nonattacking queens in a rectangular strip, with Seth Chaiken and Thomas Zaslavsky.
Published in Annals of Combinatorics. Volume 14, pp 419–441. (2010) [doi:10.1007/s00026-011-0068-7]
  • WIGG.txt : A file that explains the functioning of WIGG.java and WIGG.mws.
  • WIGG.class : A compiled java program to calculate a formula for the number of nonattacking configurations of chess pieces on an m x n board through weighted integral gain graphs; outputs Maple input. [The uncompiled files: wigg.java, graph.java, edge.java, node.java.]
  • WIGG.mws : A Maple worksheet used to calculate the generating functions for the number of nonattacking configurations of chess pieces. Requires John Stembridge's SF package.
7. (pdf) The enumeration of fully commutative affine permutations, with Brant C. Jones. (Also available as a Poster.)
Published in European Journal of Combinatorics. Volume 31, pp 1342–1359. (2010) [doi:10.1016/j.ejc.2009.11.010]
  • affineFC.nb (pdf version) : A Mathematica file that calculates the generating function by rank and length of the fully commutative affine permutations.
6. (pdf) Ensuring every candidate wins under positional voting.
Published in Social Choice and Welfare. Volume 33, pp 311–333. (2009) [doi:10.1007/s00355-008-0359-z]
  • BordaExamples.mws : A Maple worksheet verifying that the disordering sets of voter preferences are indeed disordering.
