  2. 2. The idea of computation Whitehead & Russell ~1910 2a = b true true “rule” a = b/2 divide by 2 true true true axiom formal process of proof:
  3. 3. Principia Mathematica axiom true true true true true true true true true Kurt Gödel: I am true, but not provable
  4. 4. Turing and the Enigma “XTYENSODNEADF…“Attack at dawn…” “Need refueling soon” “TEHDIENENEEE” possible mappings:
  5. 5. universal computation every possible mapping all possible mappings: “AAAAAAA” “AAAAAAB” … “ZZZZZZZY” “ZZZZZZZZ” Any: “AAAAAAA” “AAAAAAB” … “ZZZZZZZY” “ZZZZZZZZ” Any: Konrad Zuse

  10. 10. expert system vs. artificial intelligence (that I want) • specific goal • well defined boundary cases • single purpose • very vague goal • no boundary case • multi purpose • does change during its lifetime vs

  13. 13. What to evolve? grammar L system code ANN genetic programming Markov Model -unpredictable mutational effect range -almost all mutations deleterious -exploding number of weights to optimize -fixed topology -over growth -hard to train -no bound on hidden states -Baum Welch Fix: evolvable code Fix: NEAT Fix: pruning
