 \, Duffy\, Lidbetter\, Messinger\, and Nowakowski introduced the\nfollowin
 g variation of a chip-firing model on a graph. At time zero\,\nthere is an
  integer number of \"chips\" at each vertex. Time proceeds\nin discrete s
 teps.  At each step\, each edge is examined (in parallel)\n-- one chip is
  moved from the greater end to the lesser end if the\nends are not equal.
