seqfun folks,
i am finally getting around to documenting
my "theme one" program in a more coherent
and detailed way.
this may be of interest to seqfan people
for the following ordered pair of reasons:
1. the data structure that it uses is a very pretty species of graphs,
"painted and rooted cacti" (parcae), which has yet to be enumerated.
2. it uses these cacti for two purposes: logical (boolean fns, prop calc)
and lexicographic, the latter implementing a type of "adaptive indexer"
for 2-level formal languages, of which initial segements of integer
digit sequences are one very interesteing special case. true story:
i once typed a good sized chunk of the 1st edition eis handbook into
an earlier version of this program.
this is 1989-vintage code -- still, it was a very good year --
and just the barest hint of a prototype, but i am hopeful
that some sharp folks might be able to do something with
the basic ideas.
here are some initial links to the source code,
plus a beginning exposition of the data struct:
