Given that the LCAU programs are used in ongoing research, the list of options will vary from time time; this is particularly true in view of the fact that the alphabet of options is now nearly full.

One item of research has concerned the fact that totalistic rules seem to follow a different probability distribution, distinct from that of general rules. At one point this was considered to be an explanation of the Chaté-Manneville effect, but was later seen to have a secondary importance.

Another item of research concerns the details of the mean field curves for automata in Wolfram's Class IV, such as Life , which can be studied in .

Some of the scarce remaining symbols have been allocated to generating specific regular configurations or specific rules (such as Life ).
