 :\n\nIn 2016\, Duffy\, Lidbetter\, Messinger\, and Nowakowski introduced t
 he\nfollowing variation of a chip-firing model on a graph. At time zero\,\
 nthere is an integer number of \"chips\" at each vertex. Time proceeds\ni
 n discrete steps.  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.\n
