Alan Turing proved in 1936 that a general algorithm to solve the halting problem for all possible … See more The halting problem is a decision problem about properties of computer programs on a fixed Turing-complete model of computation, i.e., all programs that can be written in some given programming language that … See more In his original proof Turing formalized the concept of algorithm by introducing Turing machines. However, the result is in no way specific to them; it … See more Many variants of the halting problem can be found in computability textbooks.

In April 1936, Alonzo Church published his proof of the undecidability of a problem in the lambda calculus. Turing's proof was published later, in … See more A typical method of proving a problem to be undecidable is to reduce it to the halting problem. For example, there cannot be a general algorithm that decides whether a given statement about natural numbers is true or false.

WebThe halting problem depends on what type of algorithms we are considering. This problem in turing machines is undecidable. Conversely, on finite state automata, the halting problem is decidable since all finite-state automata halt. And therefore it is important to specify a model. Proving the halting problem.
