[gecode-users] Filling up a matrix ...

[Claudio Cesar de Sá]

Hi,

My program consist in filling up of a matrix  (nxn) with 0 and 1 with under
3 rules;

1. In each col presents at least one (1) ...
2. In each row presents at least one (1) ...
3. Where these 1´s appears,  the indexes (i,j) must be checked in the graph.

The rule number 3 I think to use an extensional constraint such:

for ....
     if pair (i,j) != 0
        extensional(*this, pair(i,j), TUPLE_SET_2_OF_A_GRAPH)


Any guess (tip) to solve 1 and 2 ??


Thanks


claudio
