We prove a characterization of all polynomial-time computable queries on the class of interval graphs by sentences of fixed-point logic with counting. More precisely, it is shown that on the class of ...

Recent work by Marcus, Spielman and Srivastava proves the existence of bipartite Ramanujan (multi) graphs of all degrees and all sizes. However, that paper did not provide a polynomial time algorithm ...

A comprehensive collection of interactive examples showcasing React Sigma.js features and capabilities for graph visualization. This gallery demonstrates everything from basic graph creation to ...

Inductive query answering is the setup where at inference time an underlying graph can have new, unseen entities. In this paper, we study a practical inductive setup when a training graph is extended ...
