こんにちは。今日は競技プログラミングで頻出（たぶん）の最短経路問題 を、BFSとDijkstra's algorithmというアルゴリズムで解いてみます。 扱う題材はAtCoder「競プロ典型90問」からの次の二問です。 辺に重みがない時の最短経路の計算には幅優先探索（BFS）を ...

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 ...

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 ...

This project is a C implementation of Dijkstra's shortest path algorithm using a specialized "Working-Set Heap" data structure. The WorkingSetHeap is a conceptual implementation of the ...

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 ...
