Twenty Years

A.s.a. H. has now become a twenty year long project (and still going).  

Hierarchical planning

Chaining of cases is possible on each level of A.s.a. H.'s hierarchical case-based memory.* This allows for hierarchical planning** at various orders of abstraction. On lower levels of the memory hierarchy this involves subsymbolic representations. On a higher level this can involve natural language.*** Reasoning can be sped up in this way.
