John Conway’s Game of Life
Rule of John Conway’s Game of Life
Birth – A dead cell with exactly three live neighbors
becomes a live cell
Survival – A live cell with two or three live neighbors stays
alive
Overcrowding or Loneliness – In other cases, a cell dies
or remains dead



Each cell considers 8 neighbors adjacent to itself
Many interesting patterns based on a same rule
(glider, exploder, pump, and etc)
We want to change the rule or GOL itself!!
21st Century is Internet Era




We are connected to the network
We don’t have to be in the same place for the
communication
We have a chat with foreigners in our room
Loneliness is not the problem of physical distance
⇒ Redefinition of neighbor
Redefinition of Neighbor




Neighbor need not to be near the cell
We make new neighbor patterns
Different patters make different GOL
Redefinition of neighbor make GOL more interesting

Edwin Martin’s Game of Life v1.3
Java Applet
Randomly generates initial patterns
Change the definition of neighbor
One neighbor goes to right
P1



P2
We have a separated neighbor
Neighbor goes to right
What will happen?

Almost cells die like P1
But shorter alive generation
Farther neighbor make life time shorter?

Yes, farther neighbor make life time shorter!!
Almost cells die like P1 and P2

We propose a new Game of Life by redefining the
pattern of neighbor
One separated neighbor cases are simulated
Farther neighbor make the life time of overall lives
shorter
We have to take care adjacent neighbors even if we
have good network for communication ^^
Other patterns of neighbor need to be simulated
