AI Seminar 2 ``Bugs and Errors in Subtraction: An Information Processing Approach'' Rakhi Banerjee (25-10-02)


In this seminar, I will present a theory of bug generation which has been modelled using the information processing approach. The domain of this theory is subtraction but it is claimed to be domain independent. I will explain the difference between a bug and an error and also describe the idea of a production system. Lastly I will explain the components and the architecture of the theory and discuss the adequacy of the theory.
