to a pairing function) code well orderings... | {"url":"http://mathoverflow.net/questions/112651/how-many-well-orderings-of-aleph-0-are-there/119387","timestamp":"2014-04-17T07:48:42Z","content_type":null,"content_length":"76160","record_id":"<urn:uuid:e5f3499c-d926-485b-aa00-95644f2e7461>","cc-path":"CC-MAIN-2014-15/segments/1397609526311.33/warc/CC-MAIN-2014041600... |
Foundations of Complexity

To properly classify problems we will sometimes need to define models of computation that do not exist in nature. Such is the case with nondeterminism, the topic of this lesson.
A nondeterministic Turing machine can make guesses and then verify whether that guess is... | {"url":"http://blog.computationalcomplexity.org/2002/12/foundations-of-complexitylesson-9.html","timestamp":"2014-04-19T22:55:07Z","content_type":null,"content_length":"145056","record_id":"<urn:uuid:14a54794-7301-4b2e-a490-7267e7c7ca82>","cc-path":"CC-MAIN-2014-15/segments/1397609537754.12/warc/CC-MAIN-20140416005217-... |
