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!!!!
