In such cases, the fastest known shortest-path algorithm doesn’t work. For decades, fast algorithms for finding shortest paths on negative-weight graphs have remained elusive.

Two computer scientists found — in the unlikeliest of places — just the idea they needed to make a big leap in graph theory.

Graph algorithms and sparsification techniques have emerged as pivotal tools in the analysis and optimisation of complex networked systems.

A new algorithm efficiently solves the graph isomorphism problem, which has puzzled computer scientists for decades.

Planar graph algorithms constitute a pivotal area in theoretical computer science, addressing problems where graphs can be drawn on a plane without edge crossings. Among the myriad challenges in ...

Then, it runs the graph algorithm on that small graph, with the algorithm treating the small graph as a portion of a larger, synthetic graph that does not exist. This method, the KAIST researchers ...

Knowledge Graph Algorithm Update Summer 2019 (a.k.a. Budapest) In July/August 2019, two things changed with Google's Knowledge Graph API that may be a turning point both for Google and for us as ...
