#Game of life python code update#

In the update operation, look only at those cells that were added to the set in the course of the previous update operation. Whenever you change a cell from live to dead or vice versa, add it, and all its neighbours, to the set. Instead of examining all cells to see if they need updating, maintain a set of cells that need to be looked at. You can take advantage of this fact to speed up the update operation. It's a feature of the game of Life that, most of the time, very few cells are changing. Then a cell can be represented by a single number instead of a pair lookups are of the form array instead of array, and adjacent cells may be found by simple arithmetic operations. When you have a program like this that operates on a two-dimensional array of cells, it often simplifies matters if you represent the two-dimensional array as a one-dimensional list.

See the paste method in section 3 below for how to decode this kind of picture.

It would be better to draw a "picture" and write a bit of code to decode it into the values you want: glider = '''.o Giant blocks of values like this are hard to input and hard to check. Instead of: if cell = True:Īnd instead of: if board = False: It's almost never necessary to compare values explicitly against True or False. This is the kind of program that really requires the use of a graphics toolkit like PyGame to draw and animate it. It's horribly tedious to watch the progress of the cellular automaton coming out on the terminal. It is therefore crying out to be implemented in the form of a class. This program consists of persistent state (the board) together with a set of operations on that state. Better to put a guard in place: if _name_ = '_main_': This makes it harder to debug the program using the interactive interpreter: as soon as the module is imported, it call main() and starts running. ]Ĭan anyone suggest any improvements to optimize my code? If board = True and countSurrounding(board, row, cell) not in (2, 3):Įlif board = False and countSurrounding(board, row, cell) = 3:īoard = , Return 0 <= row < len(board) and 0 <= cell < len(board) If isInRange(board, row, cell) and board = True: is my implementation of John Conway's Game of Life in Python: from copy import deepcopy Surface = _mode((dimx * cellsize, dimy * cellsize)) Has not ended, the update function is called and the simulation continues. It initializes the program and contains an event loop with which pygame checks whether the program has been ended by the user. Num_alive = np.sum(cur) - curĮlif (cur = 1 and 2 <= num_alive <= 3) or (cur = 0 and num_alive = 3):Ĭol = col if cur = 1 else col_background The Python source code for Game of Life can be downloaded from GitHub. A dead cell is revived if it has exactly three living neighboring cells.A living cell with more than three living neighboring cells dies in the next time step.A living cell with two or three living neighbors lives on.A living cell dies if it has fewer than two living neighboring cells.In the Python example, these states are expressed by the numbers 0 and 1.įor the next time step, the states of the cells are calculated according to the following rules: Each cell in the game has one of two states: "Alive" or "Dead". The simulation starts in the first time step with a specified initial state. Kind of computer, albeit one that is extraordinarily complicated to program.

So you could say that a machine or software that implements the "Game of Life" is in itself a With a Turing complete machine, you can theoretically perform any calculation. It was later proven that the game of life with John Conway found a set of simple rules with which it is possible to create structures within the simulation that can replicate, move, or interact with each other. A detailed description of the "Game of Life" can be found in a separate article on this website. The simulation can create complex patterns using simple The new state of a cell only depends on the state of the neighboring cells in the previous time step. The simulation proceeds in discrete time steps. Cellular automata are discrete models that consist of a regular grid in which each cell has a defined state. The "Game of Life" developed by the English mathematician John Horton Conway is a cellular automaton.
