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.

Back in 1996, a computer scientist called Lov Grover at Bell Labs in New Jersey unveiled an unusual algorithm for searching through a database. Searching algorithms are among the most important in ...

Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine quantum advantage when all costs are properly accounted for. This critique is ...

Oracle-based quantum algorithms cannot use deep loops because quantum states exist only as mathematical amplitudes in Hilbert space with no physical substrate. Criticall ...

This article breaks down the machine learning problem known as Learning to Rank and can teach you how to build your own web ranking algorithm. This quote couldn’t apply better to general search ...

Google’s Freshness Update was a significant ranking algorithm change that introduced the trend of making the search results more precise and responsive to user intent. The result of the update was the ...
