SUMMARY:Algebraic Combinatorics Seminar - Jeremy Chizewer
CLASS:PUBLIC
DESCRIPTION:Title: The Hat Guessing Number of Graphs\n\nSpeaker:\n Jeremy C
 hizewer\n\nAffiliation:\n University of Waterloo\n\nLocation:\n MC 5479 in
  person\n\nAbstract:  The hat guessing number _HG(G)_ of a\ngraph _G_
  on _n_ vertices is defined in terms of the following\ngame: _n_ play
 ers are placed on the _n_ vertices of _G_\, each\nwearing a hat whose c
 olor is arbitrarily chosen from a set\nof _q_ possible colors. Each play
 er can see the hat colors of his\nneighbors\, but not his own hat color. A
 ll of the players are asked to\nguess their own hat colors simultaneously\
 , according to a\npredetermined guessing strategy and the hat colors they 
 see\, where no\ncommunication between them is allowed.
