Sprouts Notation
Posted: Jan 13, 1999 4:02 PM

Is there a standard notation for sprouts? If not, I propose that the
dots be numbered from 1 to n and that each generated dot be numbered
consecutively thereafter. Let the basic form be a-b,c, where a is the
number of the newly generated dot, b is "from" and c is "to". 9-1,2
means a move from dot 1 to dot 2, generating dot 9. If necessary,
follow this basic form with a list of enclosed dots delimited by
slashes. 9-1,2/3/ means a move from dot 1 to dot 2 which separates
dot 3 from some other dot(s). If the move is still ambiguous, add an
@ followed by a dot which the newly generated dot communicates with.
9-1,2/3/@4 means a move from dot 1 to dot 2 generating dot 9,
separating dot 3 from any other previously accessible dots and placing
dot 9 in a position such that dot 9 and dot 4 are mutually accessible.
I suggest that the first move of a game be prefixed by N (sprouts) or
O (reverse sprouts), that moves be separated by semicolons, that all
commentary be placed in square brackets, and that a game suffix be :X
(win by player 1) or :Y.
I also suggest that parsimony and low numbers be given priority.
e.g. N7-1,2; 8-1,1/3,4/; 9-2,8; 10-2,7@ [bad move]; 11-9,10 :X
