Algorithm Description
Comway's Game of Life is a algorithmic representation of cellular automation developed by John Conway in 1970. The game is played on an infinite two-dimensional rectangular grid of cells. Each cell has two probable states, alive or dead. Depending on the state of that cell's 8 neighbors, the state of each cell changes each turn of the game, constituting a unique generation on every computation . Neighbors of a cell are cells that touch that cell, either horizontal, vertical, or diagonal from that cell.
The initial pattern is the first generation. The second generation evolves from applying the rules simultaneously to every cell on the game board, i.e. births and deaths happen simultaneously. Afterwards, the rules are iteratively applied to create future generations. For each generation of the game, a cell's status in the next generation is determined by a set of rules.
Rules
The rules of the game are simple, and describe the next generation of cells in the grid:
- Birth: a cell that is dead at time t will be alive at time t +1 if exactly 3 of its eight neighbors were alive at time t
- Death: a cell can die by:
- Overcrowding: if a cell is alive at time t + 1 and 4 or more of its neighbors are also alive at time t, the cell will be dead at time t + 1
- Exposure: If a live cell at time t has only 1 live neighbor or no live neighbors, it will be dead at time t + 1
- Survival: a cell survives from time t to time t + 1 if and only if 2 or 3 of its neighbors are alive at time t
Examples
Using the above two dimensional infinite playground and rules as outline above, the following patterns emerge during various cell positions during various generations. Some possible triomino patterns (and their next generations) are:
