In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

So-called 'external memory' sorting algorithms generally look very different from in-core algorithms. IIRC, the efficient way involves setting up a 'funnel' of input data streams, and writing out ...

An algorithm used trillions of times a day around the world could run up to 70 per cent faster, thanks to an artificial intelligence created by UK-based firm DeepMind. It has found an improved way for ...
