Yes, because Ari Heljakka pointed me toward it. This technique seems to be
popular in Finland!

However, it is not oriented toward forming complex predicates satisfying
complex fitness functions (goals); I think its utility in an AI context is
probably restricted to perception processing, and general high-level
organization of concept-space...

What we use in Novamente for concept formation is a variant of BOA, which is
a probabilistically-defined variant of Genetic Algoriths / Genetic

It is thus capable, but only of formation of restricted sorts of hypotheses.
