"Breaking the Sorting Barrier for Directed Single-Source Shortest Paths" by Ran Duan, Jiayi Mao, Xiao Mao, Xinkai Shu, and Longhui Yin (2025) Use the road_network_benchmark example to evaluate the ...

Abstract: This study focuses on reformulating the shortest path problem in undirected weighted graphs into a QUBO problem, leveraging the D-Wave quantum annealing hybrid solver for execution. While A ...

Yes the darkest day of the year is here, but that means brighter days are ahead. Sunday is the shortest day of the year north of the equator, where the solstice marks the start of astronomical winter.

The 2025 winter solstice will take place at 10:03 a.m. Eastern time Sunday, Dec. 21. That’s the moment when the Northern Hemisphere is tilted the farthest away from the sun. The winter solstice is ...

Not a fan of winter's short days and long nights? Don't fret, the days are about to start getting longer again. The Northern Hemisphere's shortest day of the year, or the winter solstice, is quickly ...

The winter solstice is upon us, marking the shortest day and longest night of the year. People across the country have already faced multiple blankets of white snow where they live, but the winter ...

Shortest path algorithms sit at the heart of modern graph theory and many of the systems that move people, data, and goods around the world. After nearly seventy years of relying on the same classic ...

Abstract: This paper investigates the shortest path planning of unmanned surface vehicles (USV) in complicated marine environments. A novel path planning method called “sunlight algorithm” is first ...
