Prof. Amos Israeli. There are many alternative definitions of Turing machines. Those are called . variants . of the original Turing machine. Among the variants are machines with many tapes and non deterministic machines. . 12 computability problemiscomputableifitcanbesolvedbysomealgorithm;aproblemthatisnoncomputablecannotbesolvedbyanyalgorithm.Section12.1considers instructional . design.

Ask what is computable. Describe a Turing machine. Define Turing completeness. Computability. 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?.
