What is The Life Game ?
1970 John Horton Conway Mathematician, Cambridge University
Simulation gameThe symbol of the biological societyUnder the certain enviroment, new life is born. Under the depopulation or the state of the congestion, the cell perishes.Modeling of a living entity in space
The Rule of The Life GameA grid on the surface
Put a cell on the space labelled “P”
Decide the placement of a new cell according to the next rule
N : the number of cells around “P”
Survival : if N = 2 or 3
Death : if N <= 1 or N>=4
Birth : There isn’t a cell on “P” and N=3
Apply these rules on the all divisions on the board
at the same time
