Groundbreaking Discovery: Dramatically Reduced Space Needed for Computation
2025-06-30

MIT computer scientist Ryan Williams has made a groundbreaking discovery, overturning 50 years of assumptions about the trade-off between computation space and time. Traditional theory held that a t-step computation requires roughly t bits of memory. However, Williams proved that any problem solvable in time t needs only about √t bits of memory. This achievement relies on reducing the problem to an equivalent one that cleverly reuses space, thus compressing information. The research suggests that the bottleneck in computation isn't memory capacity, but how efficiently it's used.
