The paper marks the culmination of a long-running search to find the most efficient procedure for performing one of the most ...
A pair of mathematicians from Australia and France have devised a new way to multiply numbers together, while solving an algorithmic puzzle that has perplexed some of the greatest math minds for almost half a century.
