(Phys.org) -- As a testament to how differently things work in the quantum and classical regimes, physicists have found that a problem that is easily solved in a classical context cannot be solved at ...

Abstract: The purpose of this paper is to gain a better understanding of the structure of undecidable problems in automata theory by investigating the degree of unsolvability of these problems. This ...

Are all problems in mathematics solved? The answer is no. There are several that remain unproven, even with most mathematicians and computer scientists having a common idea about it. Time complexity, ...

The HALTING PROBLEM An undecidable Problem in Computer Science Alan Turing proved in 1936 that a general algorithm (software code) running on a Turing machine that solves the halting problem for all ...
