Andrew Yao's computational complexity theory

Andrew Yao is a prominent computer scientist known for his work in computational complexity theory, which studies the resources required to solve computational problems. Yao introduced the concept of "communication complexity," which examines how much information must be exchanged between parties to compute a function. This has applications in areas like distributed computing and cryptography. His work helps us understand the limits of efficient computation, guiding how algorithms can be designed and optimized for better performance and resource usage.
