Machines Recursive and Recursively Enumerable Languages Turing Machine 1 TuringMachine Theory The purpose of the theory of Turing machines is to prove that certain specific languages have no algorithm. 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 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 Class 15: .

How do we define what is and what is not computable?. Is it possible to write a C++ function which cannot be written using Pascal, Java, or C#, or vice versa?.
