This is documentation for Mathematica 5, which was
based on an earlier version of the Wolfram Language.

 Further Examples: CellularAutomaton This defines the function RasterGraphics. In[1]:= This gives the array of values obtained by running rule 30 for 3 steps, starting from an initial condition consisting of a single 1 surrounded by 0's. In[2]:= Out[2]= This runs rule 30 for 50 steps and makes a picture of the result. In[3]:= If all values in the initial condition are given explicitly, they are in effect assumed to continue cyclically. This runs rule 30 with 5 cells for 3 steps. In[4]:= Out[4]= This starts from {1, 1} on an infinite background of repeating {1, 0, 1, 1} blocks. By default, only the region of the pattern affected by {1, 1} is given. In[5]:= This gives all cells that could possibly be affected, whether or not they are. In[6]:= This places blocks in the initial conditions at offsets -10 and 20. In[7]:= This gives only the last row after running for 10 steps. In[8]:= Out[8]= This runs for 5 steps, giving the cells on the 3 center columns at each step. In[9]:= Out[9]= This picks out every other cell in space and time, starting 200 cells to the left. In[10]:= This runs the general k = 3, r = 1 rule with rule number 921408. In[11]:= This runs the totalistic k = 3, r = 1 rule with code 867. In[12]:= This uses a rule based on applying a function to each neighborhood of cells. In[13]:= This runs the 2D 9-neighbor totalistic code 630 for 25 steps, giving the results for the last 5 steps. In[14]:= This runs the 2D 9-neighbor outer totalistic code 746 for 200 steps, starting from a block of 7 black cells, giving the result for the last step. In[15]:= This runs the 2D 5-neighbor outer totalistic code 481 for 50 steps, giving the result for the last step. In[16]:=
