Sanjeev Arora

Digital Library

ACM Prize in Computing

USA - 2011


For contributions to computational complexity, algorithms, and optimization that have helped reshape our understanding of computation.

Sanjeev Arora is one of the architects of the Probabilistically Checkable Proofs (PCP) theorem, which revolutionized our understanding of complexity and the approximability of NP-hard problems. He helped create new approximation algorithms for fundamental optimization problems such as the Sparsest Cuts problem and the Euclidean Travelling Salesman problem, and contributed to the development of semi-definite programming as a practical algorithmic tool. He has played a pivotal role in some of the deepest and most influential results in theoretical computer science, and continues to inspire colleagues and new generations of researchers.
