The Options tab for the infinite 1-D Automata looks like,
and the Options tab for the finite 1-D Automata looks like,
We will discuss each of the options in the order they appear.
Automata: This is simply a selection between generating a finite or infinite automaton.
Alignment: If you are creating an infinite automaton you can set the
way the data is arranged. The pin alignment will arrange the data in a manner
similar to the way we usually write Pascal's Triangle. For example,
The same data aligned in a column alignment would look like,
Update: If you are creating a finite automaton you can set the update rule to either wrap or not wrap. The process of wrapping is discussed in the Overview of 1-D Cellular Automata.
Draw: Simply sets the drawing mode to circles or squares.
Number of Rows: Sets the number of rows that are created past the seed rows. So if you have one seed row and the number of rows is set to 100 you will graph a total of 101 rows.
Default Element: In the Overview of 1-D Cellular Automata you saw that
whenever the update rule went "outside" the automaton it used the group identity in
the update calculation. Furthermore, as you can see on the page discussing the
seed options, if there is a seed entry that is left blank some element must be placed
there as well. This program allows the user to select the element that is to be used
"outside" the automaton and in the blank spaces of the seed entries. This is
the Default element. In most cases you will use the group identity but the
program does not force this choice. Simply input the element you wish to use as the
default. If you want to use the group's identity simply click the Use Group Identity
button and the identity element will be loaded into the text box. If you
are working with a user-defined structure it is possible that there does not
exist a unique identity element. In that case a message box will appear telling
you so.
