Let me quote from Modeling with Gecode:
Never ask for solutions to homework. The only more
offensive thing you could do is to provide a solution on the
mailing list if someone has violated the no homework policy!
Apart from that, your question is not specific to Gecode.

Subject: [gecode-users] Help me with Maximum density still life in Gecode
Hi All,
I am stuck on this Maximum density still life problem with Gecode. I use
this constraint
post(*this,
tt(imp(m(i-1,j-1)+m(i-1,j)+m(i-1,j+1)+m(i,j-1)+m(i,j+1)+m(i+1,j-1)+m(i+1,j)+
m(i+1,j+1) == 3,m(i,j)==1)));
post(*this,
tt(imp(m(i-1,j-1)+m(i-1,j)+m(i-1,j+1)+m(i,j-1)+m(i,j+1)+m(i+1,j-1)+m(i+1,j)+
m(i+1,j+1) < 2,m(i,j)==0)));
post(*this,
tt(imp(m(i-1,j-1)+m(i-1,j)+m(i-1,j+1)+m(i,j-1)+m(i,j+1)+m(i+1,j-1)+m(i+1,j)+
m(i+1,j+1) > 3,m(i,j)==0)));
However, it is only with 7*7 board. For 8*8 board, my program run very
slowly. I am trying to improve by dividing the board into 3*3 squares but
still do not have solution
Anyone give suggestion, Thank you very much!!!!
