Algorithms that zero in on solutions to optimization problems are the beating heart of machine reasoning. New results reveal surprising limits. Our lives are a succession of optimization problems.

For non-planar graphs, such solutions are computationally intractable," explained the researchers. The algorithm relies on the Kac-Ward formalism, a mathematical method that allows exact computation ...

Google's using a machine learning technology called RankBrain to help deliver its search results. Here's what's we know about it. Google uses a machine-learning artificial intelligence system called ...
