Is next time complexity sub-exponential? $O(2^{N^{LOG2(1.5)}}/8)$ unformatted: O((2^N)^LOG2(1.5))/8) just in case I didn't format it properly.

https://cstheory.stackexchange.com/a/3627/32204 Could someone explain to me why this reasoning is false. I don't understand it! To me this sounds plausible!

Assuming the Exponential time hypothesis is true, what's the fast possible algorithm that can be produced for NP-complete problems? If 3-Sat takes exponential time, then could it be possible that ...

In terms of worst-case asymptotic runtime, which NP-complete problem has the fastest-known (exact) algorithm and what is the algorithm? Is there something known that is faster than $O(n^2*2^n)$?

This question asks about NP-hard problems that are not NP-complete. I'm wondering if there exist any decision problems that are neither NP nor NP-hard. In order to be in NP, problems have to have a ...

I am a starter in complexity theory though I have fair knowledge in Turing machine. I know what it means to be non-deterministically polynomial time solvable but I am trying to understand where the ...

Dynamic Programming seems to result in good performance algorithms for Weakly NP-hard Problems. Two examples are Subset Sum Problem and 0-1 Knapsack Problem, both problems are solvable in pseudo-...

$3$-$\mathrm{Partition}$ problem is $\mathsf{NP}$-Complete in a strong sense meaning there is no pseudo-polynomial time algorithm for it unless $\mathsf{P=NP}$. I am looking for the fastest known ...

The quickest algorithm for solving subset sum currently is $2^{n/2}$ (via Wiki). Why doesn't this violate the Exponential Time Hypothesis which states that “there is no family of algorithms that can ...

We are given a set of $n$ numbers and want to know whether it can be partitioned to two sets with an equal sum. To prove that an equal partition exists, it is sufficient to show a partition. What is ...

When an algorithm is said to be subexponential - does this refer to the input N or the number of bits used to represent N? Consider the following: trial division for integer factorization (i.e. try ...

If the complexity of an arbitrary algorithm to solve any NP problem after analysis is $\Theta(2^\sqrt{n})$ then is this algorithm considered as "good" and practical algorithm? I know that in ...

According to answers here Are there subexponential-time algorithms for NP-complete problems? $\mathsf{NP}$ complete problems can be in $DTIME[2^{n^{1/\alpha}}]$ for $\alpha>1$. Now supposing $...

This "research vignette" (whatever that is) claims that the polynomial hierarchy classifies problems according to a natural notion of logical complexity, and is defined with an infinite number of ...

Here is the context of the problem I am struggling with. I have a set of strings, for example: ...
