In theory, it cannot be ruled out that the algorithms might run for longer than the age of the universe. But in practice, many algorithms seem to work just fine.

Clustering algorithms are a powerful form of AI that can be applied to business challenges from customer segmentation to fraud detection.

A new theory could bring a way to make quantum algorithm development less of an accidental process, say scientists.

Complexity Theory and Polynomial Time Algorithms Publication Trend The graph below shows the total number of publications each year in Complexity Theory and Polynomial Time Algorithms.

"These algorithms and policies that are derived from the study of matching theory have so many useful applications," she says. "Usually in mathematics there's a lot of abstraction.
