*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)));

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!!!!*
