The Seed tab looks like,
Each row of the seed represents a time-step of the automaton. If your update rule goes back only one time-step then you will need only one row in your seed. If you use more than one previous time-step in the update you may want to have more than one seed row. Recall that if the update rule must go outside the automaton (including the seed) it will use the default element.
You can set the number of rows and columns by the spinners above the
grid. The program can take a maximum of 20 rows and 100 columns. Once
the number of rows and columns are selected simply fill in the grid
with the seed elements you wish to use. For example, say we are working
in Z5, infinite automaton, our alignment is set to column, our
default element is the identity and we want the following seed.
We would change the number of rows and columns of the seed table to three
each and input the data so that our table looks like,
Once we graphed this we get the following. Note that the blank cells
in the seed table have been changed to 0, the identity element in Z5.
If we change the alignment to pin and regraph the automaton we get the following.
It looks the same except that in the pin alignment the top is pushed over a bit.
There are five tools for the seed tab.
