Algorithms are central to modern mathematics and computer science. They are explicit procedures valued for their clarity, ...

In 1996, Dor, Halperin, and Zwick introduced an influential method that delivered a “2-approximation” in nearly optimal time. Its estimate would not exceed twice the true shortest distance. If two ...

In life, we sometimes have to make decisions without all the information we want; that’s true in computer science, too. This is the realm of online algorithms — which, despite their name, don’t ...

Using a sequence of steps to solve a problem. Scientific applications, forecasting, decision making, quantum computing and AI use algorithms routinely. Computer programming is used to implement the ...
