 Copy-mutate one CA view to other 8 CA views.

Additional Notes

Please download JDK/JRE v1.4.1 or higher for better applet performance.

Discrete CA: Use pages 55, 56 from A New Kind of Science for rule reference. (*Only available for Discrete Valued CA)

Continuous CA: Use pages 155 168, 243 to experiment different CA rules. Continuous CA use Rule: NewC = [(Left  Weight * L + C + Right Weight * R) / 3 + Inc] MOD 1

Tips for Wave Equation Pattern:

  • Select Continuous CA from States Menu.

  • Select Seed Menu for Diffusion. (This will smooth out the CA pattern)

  • Select Seed Menu for Wave Equation. (For Sine Wave Pattern, select Sine Wave Cells, then select Wave Equation again)

  • Change color options to see different color patterns.
