The question is already quite long, with two different formulations. And I noticed that my own answer to my question is not 100% correct.
Consequently I would like the question to get some new attention. Now I could
Completely trim and reformulate the question and remove or mark my answer as ...
Question: Show that there is an oracle A and a language L ∈ NPA such that L is not polynomial-time reducible to 3SAT even when the machine computing the reduction is allowed access to A.
I am stuck at this question. It is an exercise from Sanjeev Arora and Boaz Barak.
The following is an exercise which I am stuck at ( source: Sanjeev Arora and Boaz Barak; its not homework ) :
Show that there is an oracle $A$ and a language $L \in NP^A$ such that $L$ is not polynomial-time reducible to 3SAT even when the machine computing the reduction is allowed access to ...
A recent question asks whether relativization is well-defined. This question wonders how to put one use of it on firmer ground.
In the BGS 1975 proof that there exists a language $B$ such that $P^B \neq NP^B$. To best available knowledge, what complexity class is $B$ in?
Fill in the bla...
I am interested in the complexity of the following problem:
SQUARE-PRODUCT
INSTANCE: Two sets $A=\{a_1,\ldots,a_n\}$ and $B=\{b_1,\ldots,b_n\}$ of non-negative integers, a positive integer $k \le n$ and a positive integer $\Delta$.
QUESTION: is there a subset $S$ of $\{1,\ldots,n\}$ of size $...
hey guys, so I'm reading through this book : Compiler Construction, Principle and Practice by Kenneth C. Louden In Chapter 6 (semantic analysis) example 6.2, the following grammar is given:
