ダイクストラというフレーズはその有名なアルゴリズムで覚えている。そのアルゴリズムを作ったのがエドガー・ダイクストラである。それ以外にも排他制御で有名なセマフォを考案している。そして「構造化プログラミング」を提案し、それにまつわるgoto ...

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 ...

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 ...

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 ...

Discrete Mathematics is a subject that has gained prominence in recent times. Unlike regular Maths, where we deal with real numbers that vary continuously, Discrete Mathematics deals with logic that ...

Urban transport systems, such as metros can provide efficient mobility for densely populated areas. Having access to reliable public transportation is not only for convenience but it can also have a ...
