Hi Mike,

Surely a good way to produce seeds different from other players. I never tried it. As you know, I first produce seeds out of the symmetry of given.

Well, for i+j > ~5 it doesn't work well. I use both methods. Sometimes both work, sometimes neither.

i took my 6.8 "diamond",
-r9c1 ==> "seed" (with 2-answers-or-more)
and this produced my 2 posts (4.0 and 6.8)

    it also produced 5.2/3.6/3.4
    ("more" except i was away;
    then again, Patrice had a better 5.2
    which did not get into "more")

Hmmmm. . . I found the -gop option for gsf sudoku that looks (to me) as though it will generate a vicinity search. Can any of you confirm, and also give me a sample command line? I'm not sure of its usage. Here's the pertinent section:

o +/-NX...: a sequence of -N and/or +N operands with option suffixes.
-N: delete all combinations of N clues; +N: add all combinations
of N clues. Puzzles are checked for single solution after each
addition phase. X may be one or more of the following options.
Each occurrence toggles the previous value. Values are inherited
by subsequent operands in the sequence. X may be one or more of:
a assume the last +M clues have already been cleared for @
c use the -Fc format with no filtering, otherwise use the
default -f format, -q constraints, and -e filtering
e do not check off subpuzzles for duplicates
i add implicit (superfluous) candidates, otherwise skip them
n show off/on ops but do not execute
o list one generated puzzle per input puzzle
p the input puzzle is a pattern -- only change original clues
r -nX random {-N+M} operations per input puzzle
@I start at clue index I counting from 1, clearing clues from
from that index on
@ clear the last +M clues and start at the leftmost empty cell
from the cleared clues
{...}xN repeats the bracketed group N times. {...}:N repeats the
bracketed group 0 or more times until the number of clues is <= N.
Some sequences may exhaust memory. {N}* (alternatively {N}!)
repeats {-N+N} until closure (no new puzzles generated). NOTE: a
recalcitrant bug sometimes omits a small number of puzzles in
combined off/on sequences that would otherwise be listed if the
sequence were done separately; if exact results are required (no
omissions) then use separate sequences.

    i forget,
    may have used it years ago---

    try -go{-4+4}p

      sudoku -go{-4+4}p -qNF -euniq()*(23==clues)*(1==minimal) -f%%v <seed.TXT >puzzles.TXT

Thank you, Pat! I'm giving this one a try. The first run appears to be somewhat promising.

I'm still not sure I understand the bracketed numbers ({-4+4}, etc.). Is that the same as the depth? What does it signify?

Sorry, I can't help you there, as I don't use gsf's codes.
