What are the graph classes which takes logarithmic space in $|V|$ in circuit representation?
The $\text{SCR}$ representation of a graph $G=(V,E)$ is $C_{G}$ id the following conditions hold:
$C_{G}$ is a combinatorial circuit with memory.
$C_{G}$ has two inputs of length $n$ bits.
$C_{G}$ ...

Storing relations space efficiently?
Let $f$ be a binary relation defined on set $S$, which contains numbers from $1$ to $n$. It is also given that number of $|\text{Img}(f)| \le k$. I want to store the function $f$ such in way such that ...

Compact mapping from an involuted set
Let $S$ be a set (say positive integers $\leq$ N) and $f$ an involution ($f$ is bijective, $f\cdot f=id$, e.g. xor with a constant). $g$ is a idempotent mapping choosing an arbitrary representative ...

Looking for a succinct dynamic sorted dictionary
I was digging through research articles to find a data structure that solves the dynamic sorted dictionary problem (representing any subset $S$ of a universe $U = \{0, \ldots, u\}$ with member/...

Succinct data structure to return occurences of letters until an index
I want to try and use a succinct type data structure in order to find the amount of occurences of a letter $C$ in a string $S$ until a given index $I$.
Assume we have a string $S$ of length $n$ over ...

Heap-like notation of a BST (BFT bit-vectors) for succinct representation
I'm researching the topic of succinct tree representations right now and came across this presentation. On slide 17 there is an example of heap-like notation of a BST (using BFT bit-vectors) and the ...

Generalization of XOR Linked Lists
Are there any results generalizing XOR Linked Lists to other types of data structures?
For example, just like an XOR Linked List requires two pointers and can iterate a 1 dimensional list, I can ...
