Turing Machines and The Halting Problem (Part 2)

The Halting Problem has fascinated thousands of computer scientists from around the world. A major part of Computing Logic, the proof of the halting problem proves that computers can't do everything. Check out the video to learn more about why computers work the way they do! For Turing Ma

Turing Machines & The Halting Problem (Part 1)

In the year 1900, David Hilbert gave a list of 23 mathematics problems for the mathematicians of the new generation. His tenth problem proved to be an enigma for many years until Alan Turing solved it while simultaneously creating the modern computer. Watch the video to see how Alan Turi

Impossible Programs (The Halting Problem)

Some programming problems are so hard that they’re impossible. We look at the first problem to have been proved undecidable, the halting problem, which was instrumental in forming the basis of the modern computer. Created by: Cory Chang Produced by: Vivian Liu Script Editors: Justin Chen,

Let XNLP be the class of parameterized problems such that an instance of size n with parameter k can be solved nondeterministically in time f(k)n to the power of O(1) and space f(k) log(n) (for some computable function f). We give a wide variety of XNLP-complete problems, such as List Colo
