PDF-Turings World 30 An Introduction to Computability Theory Lecture Notes

Turings World is a selfcontained introduction to Turing machines one of the fundamental notions of logic and computer science The text and accompanying diskette allow the user to design debug and run sophisticated Turing machines in a graphical environment on the Macintosh Turnings World introduces users to the key concpets in computability theory through a sequence of over 100 exercises and projects Within minutes users learn to build simple Turing machines using a convenient package of graphical functions Exercises then progress through a significant portion of elementary computability theory covering such topics as the Halting problem the Busy Beaver function recursive functions and undecidability Version 30 is an extensive revision and enhancement of earlier releases of the program allowing the construction of oneway and twoway finite state machines finite automata as well as nondeterministic Turing and finitestate machines Special exercises allow users to explore these alternative machines.
