3. IPA Fall Days 2007: Beyond Turing 1936: On computable numbers, with an aplication to the Entscheidungsproblem  Turing machine 1939-1940: The Bombe 1950: Computing machinery and intelligence  Turing test 1954: suicide by cyanide poisoning Alan Turing (1912 – 1954) British mathematician / computer scientist / philosopher / …

4. IPA Fall Days 2007: Beyond Turing Classical computing input output environment Turing machine / pointer machine / random-access machine  unbounded uniform memory  computations over finite alphabet  finite computations  behavior (algorithm) is fixed  no interaction with environment memory finite state machine

5. IPA Fall Days 2007: Beyond Turing Modern and/or future computing systems input output environment memory finite state machine  quantum- and other computers  no uniform, unbounded memory  systems are “always on”  interaction with environment and other algorithmic systems  environment and, hence, algorithmic systems evolve over time L1 cache L2 cache L3 cache registers main memory disk ALU environment
