Formal Grammar definition for CGA?

[PhilDesrosiers]

I'm working on a machine learning project, to evolve building designs based on some user-defined success criteria. I'd like to persist intermediate results as a CGA ruleset, then use those as inputs to subsequent generations. Is there some formal, BNF-Like (or Yacc, or ANTLR, or whatever) definition for CGA grammar, other than the very helpful (but not very formal) CGA Reference Index ?

Hello Phil

Your project sounds very interesting. Regrettably the CGA grammar definition can not be published to external users.

Of course you can use the CGA reference to derive your own version.

Okay thanks Thomas.
