Universal Method to Sort Complex Information Found

August 13, 2018

The nearest neighbor problem asks where a new point fits into an existing data set. A few researchers set out to prove that there was no universal way to solve it. Instead, they found such a way.

Quantum Algorithms Struggle Against Old Foe: Clever Computers

February 1, 2018

The quest for “quantum supremacy” – unambiguous proof that a quantum computer does something faster than an ordinary computer – has paradoxically led to a boom in quasi-quantum classical algorithms.
