Hi,
I am using the example in the documentation, where the list of words is
explicitly provided:
const int n_words[] = {
1, 26, 66, 633, 2443, 4763, 7585, 10380, 10974
};
so hopefully a dictionary big enough.
I will try to use the command suggested. Do you think that imposing 20 or 30
letter constraints like that is a problem?
Cheers,
Andrea

This might depend on the dictionary you are using. Check whether it contains
words with the corresponding letters. Note that you can give your own
dictionary as a file, check examples/crossword.cpp that comes with Gecode.
Anyway, I would not overwrite the variables but constraint them such as in
rel(*this, ml(10,5) == âfâ);
and so on.
Cheers
Christian

Subject: [gecode-users] GECODE: Crosswords with two constraints, set letters
and black cells
Hi all,
I am having a look at the examples of crosswords in Gecode. I am doing this for
a gift. So the satisfaction of getting it done would be even greater!
I would like to add another set of constraints, not just black cells but also
specific letters on the grid (which I would like to use to arrange a secret
message that the receiver will read after having solved the crossword).
I tried this (just an example):
IntVar letter1(*this, 'f', 'f');
ml(10, 5) = letter1;
IntVar letter2(*this, 'i', 'i');
ml(9, 4) = letter2;
Running the example of Figure 22.2 of the documentation (Chapter 22) works fine
if I impose only two constraints like the above, but everything already
collapses if I try to set three letters.
Do you think what I am thinking of is feasible? I mean, I would like to fix 20
or 30 letters on a 22x15 grid, but it seems that I am not even close to getting
a solution.
I am trying to read through the documentation but by scarcity of time I am not
sure if I am trying the impossible or simply I have to tweak other parameters.
Could you please help me?
Cheers,
Andrea
