PPT-1 Turing Machines Reading: Chapter 8

2 Turing Machines are Very powerful abstract machines that could simulate any modern day computer although very very slowly Why design such a machine If a problem cannot be solved. They provide a precise formal de64257nition of what it means for a function to be computable Many other de64257nitions of computation have been proposed over the years for example one could try to formalize precisely what it means to run a program A Turing machine is a primitive yet general computer with an in64257nite tape In each cycle the control unit reads the current tape symbol writes a symbol on the tape moves one position to the left or right and switches to the next state The last th What we have learned. The failures of dualism, behaviorism, and identity theory were not in vain!. Each failure reveals important features of mental states that any theory ought to be able to handle.. Announcements.
