Ðề: P ≠ NP? It's bad news for the power of computing Có vẻ như mọi chuyện đã ngã ngũ: | Trích: |  | | | I think there are several levels to the basic question “Is the proof correct?”: - Does Deolalikar’s proof, after only minor changes, give a proof that P
NP? - Does Deolalikar’s proof, after major changes, give a proof that P
NP? - Does the general proof strategy of Deolalikar (exploiting independence properties in random
-SAT or similar structures) have any hope at all of establishing non-trivial complexity separation results? After all the collective efforts seen here and elsewhere, it now appears (though it is perhaps still not absolutely definitive) that the answer to #1 is “No” (as seen for instance in the issues documented in the wiki), and the best answer to #2 we currently have is “Probably not, unless substantial new ideas are added.” But I think the question #3 is still not completely resolved, and still worth pursuing (though not at the hectic internet speed of the last few days.) | | | | |
