conways-game-of-life

问题 I have been playing around with Conway's Game of life and recently discovered some amazingly fast implementations such as Hashlife and Golly. (download Golly here - http://golly.sourceforge.net/) One thing that I cant get my head around is how do coders implement the infinite grid? We can't keep an infinite array of anything, if you run golly and get a few gliders to fly off past the edges, wait for a few mins and zoom right out, you will see the gliders still there out in space running away,

问题 To experiment, I've (long ago) implemented Conway's Game of Life (and I'm aware of this related question!). My implementation worked by keeping 2 arrays of booleans, representing the 'last state', and the 'state being updated' (the 2 arrays being swapped at each iteration). While this is reasonably fast, I've often wondered about how to optimize this. One idea, for example, would be to precompute at iteration N the zones that could be modified at iteration (N+1) (so that if a cell does not

问题 I want a twodimensional array in Ruby, that I can access for example like this: if @array[x][y] == "1" then @array[x][y] = "0" The problem is: I don't know the initial sizes of the array dimensions and i grow the array (with the << operator). How do I declare it as an instance variable, so I get no error like this? undefined method `[]' for nil:NilClass (NoMethodError) QUESTION UPDATED: @array = Array.new {Array.new} now works for me, so the comment from Matt below is correct! I just found

问题 I want to memory-efficient this (the game of life code of shiffman in the nature of code book). how can change the below code to have only two arrays and constantly swap them, writing the next set of states into whichever one isn’t the current array? class GOL { int w = 8; int columns, rows; int[][] board; GOL() { // Initialize rows, columns and set-up arrays columns = width / w; rows = height / w; board = new int[columns][rows]; //next = new int[columns][rows]; // Call function to fill array

问题 I am trying to make a game of life simulation using Java Graphics but when a run my code the left one third of the screen is grey.I want the whole screen to be white with black squares representing living squares. I am confused about all the java containers/panels and frames. Here's my code: public class ConwayGame { static JPanel panel; static JFrame frame; public static void main(String[] args) throws InterruptedException{ int [][] array = new int [40][40]; /* * Set the pattern for Conway's

问题 I've been working on a Game of Life assignment and am nearing the stage of completion, but am struggling to figure out what I've messed up on such that the GOL rules (and Fredkin rules that the assignment requires us to implement as well) are not generating the proper result. As I have little experience working with graphics I decided to output everything in the interactions window (using Dr.Java). (It's used to set up menu options like the scale, coordinates (you manually enter), generations

问题 I was assigned this project with instructions below: The game of Life is defined for an infinite-sized grid. In Chapter 2, we defined the Life Grid ADT to use a fixed-size grid in which the user specified the width and height of the grid. This was sufficient as an illustration of the use of a 2-D array for the implementation of the game of Life. But a full implementation should allow for an infinite-sized grid. Implement the Sparse Life Grid ADT using an approach similar to the one used to
