Computational complexity and computability are central themes in theoretical computer science that address the fundamental question of what can be computed and at what cost. Computability theory ...

Theoretical computer scientists are always probing the relationship of space (memory) and time. For 50 years, experts knew that a calculation of X steps required X/log X memory slots, but a new study ...

One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling discovery about the relationship between time and memory in computing.
