Expectations
More Complex Functions
Flexibility, Robustness
Adaptivity, Evolability
Autonomy
User Friendliness
Situation Awareness
Life as Model
• Living Cell: as complex as PC, but flexible, robust, autonomous, adaptive, evolvable, situation aware
• Organism: more complex than all existing software
• Human Brain: intelligent, conscious, creativeIt is the source of all algorithms!!Estimated computing power: 1015 OPS PC today 109 OPS, will equal brain in 30 years according to Moore‘s Law
• But: Life is not digital, not deterministic, not algorithmic
A new computing paradigm –
• From Algorithms …Arithmetic, Accounting, Differential Equations
• … To SystemsCoordination of Sub-ProcessesCommunicationPerceptionAutonomous Action
Organic Computing:
Organic Computing is not
Molecular computing,
about faster computers
but
being fault-tolerant and self-organizing,it will lay the foundation for molecular and massively parallel computers
Human:
Detailed Communication
Machine:
Creative Infrastructure: Goals, Methodology, Interpretation, Diagnostics
Algorithms: deterministic, fast, clue-less
Algorithmic Division of LaborAlgorithmic
DOL
Debugging
Comparison of actual result with original goal
Autonomous debugging:
Goals must be represented in the machine
