Universal Turing Machines (cont.)  A Universal Turing Machine (UTM) is capable of simulating an arbitrary Turing Machine M on an arbitrary input word w.  One possible UTM is a two-tape TM that may be described as:    The UTM simulates M by locating on the program tape the appropriate transition given the current state of M and the symbol on the work tape being scanned by its head When the transition is located, the UTM carries out the operation on the work tape There is a standard UTM equivalent to this two-tape UTM w    work tape Control Unit (M)    program tape
