The Nesting Bird Box Problem is ER-complete: Sharp Hardness Results for the Hidden Set Problem

Lucas Meijer, Till Miltzow, Johanna Ockenfels, Milos Stojakovic ยท 2026

In the (Nesting) Bird Box Problem we are given a polygonal domain P and a number k and we want to know if there is a set B of k points inside P such that no two points in B can see each other. The undโ€ฆ

Small Independent Sets versus Small Separator in Geometric Intersection Graphs

Malory Marin, Remi Watrigant ยท 2026

While most classical NP-hard graph problems cannot be solved in time $2^{o(n)}$ on general graphs under the Exponential Time Hypothesis (ETH), many exhibit the square-root phenomenon and admit optimalโ€ฆ

Flashback: A Reversible Bilateral Run-Peeling Decomposition of Strings

Thomas Konstantinovsky, Gur Yaari ยท 2026

We introduce Flashback, a reversible string decomposition that repeatedly peels the maximal leading and trailing character runs from a sentinel-wrapped input, recording each pair as one bilateral tokeโ€ฆ

The Surprising Universality of LLM Outputs: A Real-Time Verification Primitive

Alex Bogdan, Adrian de Valois-Franklin ยท 2026

We report a striking statistical regularity in frontier LLM outputs that enables a CPU-only scoring primitive running at 2.6 microseconds per token, with estimated latency up to 100,000$\times$ (five โ€ฆ

Grouped Color Deletion, Lasserre Exactness and Clique-Sum Locality for Rainbow Matching

Georgios Stamoulis ยท 2026

We study the rainbow matching (RM) problem: given an edge-colored graph, find a maximum matching with at most one edge of each color. Rainbow matchings correspond to stable sets in the \emph{augmentedโ€ฆ

PSP: An Interpretable Per-Dimension Accent Benchmark for Indic Text-to-Speech

Venkata Pushpak Teja Menta ยท 2026

Standard text-to-speech (TTS) evaluation measures intelligibility (WER, CER) and overall naturalness (MOS, UTMOS) but does not quantify accent. A synthesiser may score well on all four yet sound non-nโ€ฆ
