カーナビやGoogle Mapsで当たり前に使われている最短経路計算に、40年ぶりの革命が起きました。 清華大学の研究チームが発表した新アルゴリズムは、1956年から使われ続けてきたDijkstra法の限界を突破し、理論上既存手法を上回る計算速度を実現。 計算機科学 ...

Systems Approach Last year a couple of people forwarded to me the same article on a new method of finding shortest paths in networks. Dijkstra is a legend in computer science and his algorithm, which ...

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

In our Retrobituaries series, we highlight interesting people who are no longer with us. Today let's explore the life of Edsger Dijkstra, who died at 72 in 2002. If you’ve used a computer or smart ...

If you are interested in the real-world applications of numbers, discrete mathematics may be the concentration for you. Because discrete mathematics is the language of computing, it complements the ...
