A straightforward implementation of Binary Decision Diagrams (BDDs) typically requires 12 bytes per node, with an additional 4 bytes commonly used for auxiliary data. Each node is encoded as a 4-tuple ...

There are $\binom{2n}{n} = \frac{4^n}{\sqrt{\pi n}} \cdot (1 - o(1))$ possible $n$-element subsets of a $2n$-element set. Therefore, any data structure storing such a set must use at least $2n - O(\...

I'm looking for a succinct version of the factoring problem: i.e. given integers N and k, does N have a prime factor less than k, but somehow the input takes exponentially fewer bits to input? Ideally ...

For a language $\Pi$, the traditional definition of "Succinct-$\Pi$" is the set of encodings of circuits whose truth tables are members of $\Pi$. This definition is essentially restricted (...

I am looking for approaches storing strictly increasing natural-valued functions defined on a (subset of) $[0..N]$: $$ \forall x \in X: 0 \le x \le N\\ f: X \to \mathbb N\\ \forall x,y\in X:\quad x<...

Notation: given a CNF formula A over variables X, we write $[A(X)]$ for the set of valuations $v: X \to \{0,1\}$ such that $A(X/v)$ is true, i.e. the set of valuations that makes formula A true. I ...

I want to know what is the best known lower time complexity of Succinct-CVP? The succinct version of many P-complete problems are EXP-complete and Succinct-CVP is EXP-complete too (It is because of ...

Succinct version of permanent is $NEXP$-hard (https://eccc.weizmann.ac.il/report/2012/086/) and so unlikely to be $EXP$-complete. Permanent mod $2$ is in $\oplus L$ and so succinct version is ...

We know succinct version of many $P$-complete problems are $EXP$-complete. There are standard ways to define $EXP$-complete graph problems from succinct representations of these $P$ complete problems. ...

Encoding NP-complete problems succintly often makes them NEXP-complete. I am wondering if counting the number of solutions to such a problem with a succint encoding would be any harder than solving ...

Denote $[n] \triangleq \{1,2,\ldots,n\}$. Assume we would like to have a data structure $S$ which kinda works as a dictionary from $[k]$ to $[v]$, and supports add/remove/update/query functionality, ...
