References for $\mathsf{PSPACE} \neq \mathsf{E}$ and $\mathsf{P} \neq \mathsf{NTIME}(n^k)$
In a recent blog post, Lance Fortnow dropped as a little exercise the task of proving $\mathsf{PSPACE} \neq \mathsf{E}$, using the fact that $\mathsf{EXP}$ is the closure of $\mathsf{E}$ under poly-...

Testing monotonicity for functions of the form $f :\{0,1,2\}^n\rightarrow \{0,1\}$
I am looking for a property testing algorithem for testing mononicity for functions of the form $f :\{0,1,2\}^n\rightarrow \{0,1\}$ which means that whenever $x \le y$ then $f(x) \le f(y)$ and by $x \...

Solving #SAT through TQBF
I'm not extremely proficient with counting complexity classes, but since #SAT is #P-complete, its decision version, let's call it #SAT(D) (is the number of solutions less than some $k$), is in PSPACE. ...

Computational complexity of the elementary theory of finite fields
Let $T_f$ denote the set of first-order sentences in the language of rings which are true in all the finite fields. That is, $T_f = \{\varphi \mid K \models \varphi, \text{ for every finite field } K\}...

Smoothed analysis in the Turing machine model
Smoothed analysis is usually defined using real numbers: given $n$ and $\sigma$, the smoothed runtime of an algorithm is the maximum, over all inputs of size $n$, of the runtime on the input when it ...

In what paper did Dijkstra say "with your hands in your pockets"?
I'm looking for a paper by Edsger Dijkstra (which I've read before) in which he talks about a certain mathematical argument that I can't quite remember what it was, but it was an elementary strategy ...

Channel Capacity & Dependency Graph
A single-input-single-output communication channel is to be used repetitively. Denote by $X_i \in \mathcal X$ the input at time $i$ and by $Y_i \in \mathcal Y$ the output at time $i$.
Assume the ...

Is this kind of "multi-reduction" interesting?
Given a decision problem $P$, the usual way to show that it is NP-hard is to find a known NP-hard problem $Q$, and show a polynomial-time algorithm that transforms every instance $I_Q$ of $Q$ to an ...
