Improved exploration of temporal graphs

Paul Bastide, Carla Groenland, Lukas Michel, Clement Rambaud · 2025

A temporal graph $G$ is a sequence $(G_t)_{t \in I}$ of graphs on the same vertex set of size $n$. The \emph{temporal exploration problem} asks for the length of the shortest sequence of vertices that…

Constant-depth circuits for polynomial GCD over any characteristic

Somnath Bhattacharjee, Mrinal Kumar, Shanthanu Rai, Varun Ramanathan, Ramprasad Saptharishi, Shubhangi Saraf · 2025

We show that the GCD of two univariate polynomials can be computed by (piece-wise) algebraic circuits of constant depth and polynomial size over any sufficiently large field, regardless of the charact…

How Large Language Models (LLMs) Extrapolate: From Guided Missiles to Guided Prompts

Xuenan Cao · 2024

This paper argues that we should perceive LLMs as machines of extrapolation. Extrapolation is a statistical function for predicting the next value in a series. Extrapolation contributes to both GPT su…

Simply-typed constant-domain modal lambda calculus I: distanced beta reduction and combinatory logic

Sean Walsh · 2024

A system $\boldsymbol\lambda_{\theta}$ is developed that combines modal logic and simply-typed lambda calculus, and that generalizes the system studied by Montague and Gallin. Whereas Montague and Gal…
