Separation of NP-Completeness Notions

SIAM Journal on Computing, 2001
Summary: We use hypotheses of structural complexity theory to separate various NP-completeness notions. In particular, we introduce an hypothesis from which we describe a set in NP that is \({\leq}^P_T\)-complete but not \({\leq}^P_{tt}\)-complete. We provide fairly thorough analyses of the hypotheses that we introduce.

The NP-completeness column

ACM Transactions on Algorithms, 2005
This is the 24th edition of a column that covers new developments in the theory of NP-completeness. The presentation is modeled on that which M. R. Garey and I used in our book “Computers and Intractability: A Guide to the Theory of NP-Completeness,” W. H. Freeman & Co., New York, 1979, hereinafter referred to as “[G&J].”” Previous

Cryptocomplexity and NP-completeness

1980
In view of the known difficulty in solving NP-hard problems, a natural question is whether there exist cryptosystems which are NP-hard to crack. In Section I we display two such systems which are based on the knapsack problem. However, the first one, which is highly "linear" has been shown by Lempel to be almost always easy to crack. This shows that NP-

Minesweeper is NP-complete

The Mathematical Intelligencer, 2000
NP-completeness Many programming p rob lems require the design of an algor i thm which has a "yes" or "no" ou tput for each input. For example , the p rob lem of test ing a whole number for pr imal i ty requires an a lgor i thm which answers "yes" if the input number x is prime, and "no" otherwise.

On the NP-completeness of cryptarithms

ACM SIGACT News, 1987
If we only consider problems with decimal numbers as above there is no possibility of any hardness result, because there are only 10! different assignments of digits and letters to try. Therefore we will generalize the problem slightly: the base of representation for our numbers will be given as part of the problem (expressed in unary or binary) rather

Properties of NP-complete sets

Proceedings. 19th IEEE Annual Conference on Computational Complexity, 2004., 2004
We study several properties of sets that are complete for NP. We prove that if L is an NP-complete set and S \not\supseteq L is a p-selective sparse set, then L - S is \leq pm-hard for NP. We demonstrate the existence of a sparse set S \in DTIME(22n) such that for every L \in NP - P, L - S is not \leq pm-hard for NP.
