Princípios da IA Simbólica
A estratégia fundamental que sustentou boa parte do sucesso inicial da IA Simbólica, se deve à proposta conhecida como “Physical Symbol Systems Hypothesis”, de Newell e Simon.
Physical Symbol Systems - Newell & Simon(1976)
”A physical symbol system consists of a set of entities, called symbols, which are physical patterns that can occur as components of another type of entity called an expression (or symbol structure)…the system also includes a collection of processes that operate on expressions to produce other expressions: processes of creation, modification, reproduction and destruction. A physical symbol system is a machine that produces through time an evolving collection of symbol structures.Such a system exists in a world of objects wider than just these symbolic expressions themselves “
