  • Computers Are Getting Faster But Are They Getting Smarter? No.
    No matter how fast the computer runs, the computer will never be more powerful than a Turing machine A Turing machine consists of five simple operations, a tape, and a set of symbols to write on the tape
  • Are there any known computational systems stronger than a . . .
    But if we look at runtime, quantum computation has (at least) a provable quadratic speedup over classical turing machines (grovers algorithm) In the real world we are also not restricted to serial computation Pi calculus captures parallel semantics and can also compute some problems faster than serial turing machines
  • Theoretical machines which are more powerful than Turing machines
    It is known that Turing machines are not so efficient, though they polynomially simulate classical computers Quantum computers are believed to be exponentially more efficient than Turing machines In this sense, you can beat Turing machines (if you could only build a scalable quantum computer)
  • computer science - Whats a Turing machine? - Stack Overflow
    A Turing machine is an abstract machine capable of computation From Wikipedia: Turing machines are basic abstract symbol-manipulating devices which, despite their simplicity, can be adapted to simulate the logic of any computer algorithm They were described in 1936 by Alan Turing
  • Turing Machine - Comparison With Real Machines - LiquiSearch
    Comparison With Real Machines It is often said that Turing machines, unlike simpler automata, are as powerful as real machines, and are able to execute any operation that a real program can
  • Real computers have only a finite number of states, so what . . .
    Real computers have limited memory and only a finite number of states So they are essentially finite automata Why do theoretical computer scientists use the Turing machines (and other equivalent models) for studying computers? What is the point of studying these much stronger models with respect to real computers?
  • What problems can we solve with a computer? Turing Machine?
    Designing Turing Machines Despite their simplicity, Turing machines are very powerful computing devices Today's lecture explores how to design Turing machines for various languages
