Undecidable problem - Wikipedia In computability theory and computational complexity theory, an undecidable problem is a decision problem for which it is proved to be impossible to construct an algorithm that always leads to a correct yes-or-no answer
Undecidable problems | AP CSP (article) | Khan Academy There are some problems that a computer can never solve, even the world's most powerful computer with infinite time: the undecidable problems An undecidable problem is one that should give a "yes" or "no" answer, but yet no algorithm exists that can answer correctly on all inputs
Decidable and Undecidable Problems in Theory of Computation What are Undecidable Problems? The problems for which we can’t construct an algorithm that can answer the problem correctly in finite time are termed as Undecidable Problems These problems may be partially decidable but they will never be decidable
What Is an Undecidable Problem in Computer Science? An undecidable problem is a problem that no algorithm can solve correctly for every possible input It’s not a matter of needing a faster computer or a cleverer programmer
Lecture 8: Undecidability | Theory of Computation | Mathematics | MIT . . . Showed that \ (\mathbb {N}\) and \ (\mathbb {R}\) are not the same size to introduce the diagonalization method and used it to prove \ (A_\bf {TM}\) is undecidable Introduced the reducibility method to show that \ (HALT_\bf {TM}\) is undecidable Instructor: Prof Michael Sipser
undecidable - Wiktionary, the free dictionary For example, a set of strings is undecidable if it is impossible to program a computer (even one with infinite memory) to determine whether or not specified strings are included
Undecidable Problems - ODU In fact, almost all execution-behavior-related properties we can think of are likely to be undecidable for programs in general Yet, these aren’t obscure questions These are problems that we face on a regular basis whenever we develop, test, and maintain software
