SUMMARY:Algebraic Graph Theory - Peter Dukes
CLASS:PUBLIC
DESCRIPTION:TITLE:  A threshold for fractional Sudoku completion\n\nSPEAKE
 R:\n Peter Dukes\n\nAFFILIATION:\n University of Victoria\n\nLOCATION:\n P
 lease contact Sabrina Lato for Zoom link.\n\nABSTRACT: The popular puzzl
 e game Sudoku presents a player with a\n9-by-9 grid having some numbers fi
 lled in a few of the cells.  The\nplayer must finish filling in numbers f
 rom 1 to 9 so that every row\,\ncolumn\, and 3-by-3 box contains each of t
 hese numbers exactly once.\n We can extend Sudoku so that the boxes are $
 h$-by-$w$\, and the\noverall array is $n$-by-$n$\, where $n=hw$.  The puz
 zle is now similar\nto completing a latin square of order n\, except of co
 urse that Sudoku\nhas an additional box condition.
