Shor’s algorithm is a quantum algorithm for factoring a number N in O((log N)3) time and O(log N) space, ...

Add a description, image, and links to the factorization-algorithm topic page so that developers can more easily learn about it.

Abstract: Based on the limitations of the Tree Seed Algorithm (TSA), such as its proneness to getting trapped in local optima and its relatively slow convergence speed, this study proposes an improved ...

WEST LAFAYETTE, Ind. — Trees compete for space as they grow. A tree with branches close to a wall will develop differently from one growing on open ground. Now everyone from urban planners and ...

You are the benevolent ruler of The Republic of Graphistan, and you want to modernize the roads between cities—widening them, repaving them, turning them into superhighways. But it’s complicated. When ...

An innovative algorithm called Spectral Expansion Tree Search helps autonomous robotic systems make optimal choices on the move. In 2018, Google DeepMind's AlphaZero program taught itself the games of ...

All species on Earth, both living and extinct, are related. We know this because of a biological tool called the tree of life. This "tree" takes the form of a diagram that maps the relationships ...

Ten months ago, a ranger on the Hadrian’s Wall Path discovered a shocking crime: The widely loved Sycamore Gap tree had been chopped down. Fans mourned the loss of a beautiful landmark; arborists ...
