Computability theory investigates the fundamental limits and capabilities of algorithmic processes, asking which problems can be solved by a mechanical procedure and how efficiently. Algebraic ...

Computability theory establishes which problems can in principle be solved by mechanical procedures, formalised by the Turing machine model and its equivalents. It draws a firm boundary between ...

This year a series of events around the world will celebrate the work of Alan Turing, the father of the modern computer, as the 100th anniversary of his birthday approaches on June 23. In a book ...
