We post patterns on this forum because they are considered interesting, but we rarely define what we mean by interesting.

Is this pattern interesting?

This 3 state pattern was generated by a program called Mod:

using this neighborhood:

and this step function:

Code: Select all

  public int step(int r, int c)
  {
    int count = 0;
    int i1 = 0;
    for (int i = r - 3; i < (r + 4); i++)
    {
      int j1 = 0;
      for (int j = c - 3; j < (c + 4); j++)
      {
        int nw = neighborWeights[i1][j1];
        if (nw != 0)
          count += squareCell.getNeighbor(i, j) * nw;
        j1++;
      }
      i1++;
    }
    return count % noStates;
  }
by running 25 steps starting with a single cell in state 1 (red).

For those who can compile and run java programs and wish to experiment by generating such patterns, the source code is here:

Two familiar guns:

Code: Select all

x = 35, y = 39, rule = R2,C0,M0,S2..3,B3..3,N@22A544
.A$A.A$.A7$12.A.A.A$11.A5.A$10.A2$10.A7.A$15.A$10.A7.A$11.A5.A$14.A
.A.A4$20.A$19.A.A.A$18.A.A5.A$19.A5.A2$19.A2$21.A$20.A7$33.A$32.A.A
$33.A!

Code: Select all

x = 45, y = 23, rule = R2,C0,M0,S2..3,B3..3,N@22A544
.A$A.A$.A2$5.A.A.A$10.A$5.A$12.A$5.A7.A2$9.A3.A$10.A.A$11.A$36.A$35.
