Emergence 2009: 1D Cellular Automaton Variant V
Biology 361 = Computer Science 361
Bryn Mawr College, Spring 2009
|WHAT IS IT?|
|This is a variant of rule 127.|
|HOW IT WORKS
Using Marwa's modification, I changed the to-do rule by changing the color of the patch-at -25 0 and 25 0 and came across patterns that seem to be much more complex than lines moving in one direction.
I also modified the ask patch-at 0 -1 instructions regarding pcolor setting.
|HOW TO USE IT|
Click on setup-single and setup-random and compare the outcomes.
Setup single outcomes are less surprising.
|THINGS TO NOTICE|
Something you will notice is that for most densities (especially those in the middle) it is hard to predict what pattern will come next. In this sense, this model variant shows statistical randomness. However, the patterns are not disordered.
The model also shows complexity arising from relatively simple rules. As you play with the density, patterns will seem to get more complex.
It is interesting that by changing a few rules the patterns are no longer lines moving in one direction, but dots.
|THINGS TO TRY|
|Try changing the density and compare the differences you get in patterns. I especially like the density around 48% because with each click, the patterns seem to get more complex. Also, try to observe the color of the backround across the different densities. At lower densities, the background color is black and at densities in the 90's, the background is green.|
|EXTENDING THE MODEL
|I'm still working on increasing my Netlogo skills. You may want to add a button so that you can see the continous change without stopping or having to click the setup-random button.|
