game of life help please

Hello,

I have to do for school a game named "game of life". I have a network in which are some cells alive( matric, where are live cells marked with 1 and other with 0). Rules of survival are simple:

a)if has live cell less than 2 neighbours dies of loneliness

b)if has live cell more than 3 neighbours dies from overpopulation

c)if has dead cell exactly 3 neighbours it became alive

i really don't know how to do this..:( sorry Please help me i would be very gratefull everybody.

Hi Androslo,

Here is an example implementation for your reference -

function gameOfLife(initialState, numIterations)
    % initialState: Matrix representing the initial state of the grid
    % numIterations: Number of iterations to simulate

    % Get the size of the grid
    [rows, cols] = size(initialState);

    % Initialize the current state
    currentState = initialState;

    % Define the possible neighbor positions (relative)
    neighborDeltas = [-1, -1; -1, 0; -1, 1; 0, -1; 0, 1; 1, -1; 1, 0; 1, 1];

    % Simulation loop
    for iter = 1:numIterations
        % Create a new state matrix
        newState = zeros(rows, cols);

        % Iterate over each cell in the grid
        for r = 1:rows
            for c = 1:cols
                % Count the number of live neighbors
                liveNeighbors = 0;
                for i = 1:size(neighborDeltas, 1)
                    neighborRow = r + neighborDeltas(i, 1);
                    neighborCol = c + neighborDeltas(i, 2);
                    % Check if the neighbor is within bounds and alive
                    if neighborRow >= 1 && neighborRow <= rows && ...
                       neighborCol >= 1 && neighborCol <= cols && ...
                       currentState(neighborRow, neighborCol) == 1
                        liveNeighbors = liveNeighbors + 1;
                    end
                end

                % Apply the rules of the Game of Life
                if currentState(r, c) == 1
                    % Rule a: Less than 2 neighbors
                    % Rule b: More than 3 neighbors
                    if liveNeighbors < 2 || liveNeighbors > 3
                        newState(r, c) = 0; % Cell dies
                    else
                        newState(r, c) = 1; % Cell survives
                    end
                else
                    % Rule c: Exactly 3 neighbors
                    if liveNeighbors == 3
                        newState(r, c) = 1; % Cell becomes alive
                    end
                end
            end
        end

        % Update the current state
        currentState = newState;

        % Display the current state
        disp(['Iteration: ', num2str(iter)]);
        disp(currentState);

        % Optional: Pause for a short time to visualize the evolution
        pause(0.5);
    end
end

Hope it helps.
