Until now, the only known algorithms for accomplishing certain tasks required an amount of space roughly proportional to their run time, and researchers had long assumed there’s no way to do better.

computational complexity For Algorithms, a Little Memory Outweighs a Lot of Time One computer scientist’s “stunning” proof is the first progress in 50 years on one of the most famous questions in ...

Now, a new study shows that time and space in computational terms have a similarly complicated relationship. Of course, computer scientists aren’t concerned with the fabric of space-time that ...
