  • CARMA COLLOQUIUM
  • Speaker: A/Prof. Murray Elder, University of Technology Sydney
  • Title: Sorting permutations with stacks
  • Location: Room SR202, SR Building (Callaghan Campus) The University of Newcastle
  • Time and Date: 4:00 pm, Thu, 30th May 2019
  • Abstract:
    Knuth showed that a permutation can be sorted by passing it right-to-left through an infinite stack if and only if it \emph{avoids} a certain forbidden sub-pattern (231). Since then, many variations have been studies. I will describe some of these including new work of my PhD student Andrew Goh on stacks in series and ``pop-stacks".
