The changing use of the word algorithm reflects this enhanced visibility. In fact, the meaning of this word has changed ...

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 ...

The library sorting problem is used across computer science for organizing far more than just books. A new solution is less than a page-width away from the theoretical ideal. Computer scientists often ...

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 ...
