Avi Wigderson, a computational scientist and mathematician, has been awarded the prestigious 2023 A.M. Turing Award. The award, presented annually by the Association for Computing Machinery (ACM), recognizes Wigderson’s significant contributions to the field of computer science. Along with the honor, he will receive a prize of $1 million, thanks to the support of Google.
Wigderson, who works at the Institute for Advanced Study (IAS) at Princeton University, is being recognized for his foundational contributions to the theory of computation. His work has reshaped our understanding of the role of randomness in computation and has demonstrated his decades-long leadership in theoretical computer science. This recognition follows his previous achievement of winning the Abel Prize in 2021, which is essentially the Nobel Prize for mathematics.
One of Wigderson’s major contributions is his insight into the use of randomness in algorithms. In the 1970s, researchers discovered that incorporating random choices into algorithms could improve their efficiency. However, Wigderson and his co-author, Noam Nisan, published a groundbreaking paper in 1994, challenging the prevailing belief in the necessity of randomness. They demonstrated that every probabilistic algorithm that is efficient can be replaced by a deterministic one. This revelation revolutionized the field of computer science and showed that the perceived power of probabilistic algorithms was unfounded.
Wigderson’s work extends beyond theoretical research. In his 2019 book, “Mathematics and Computation: A Theory Revolutionizing Technology and Science,” he highlights the ubiquity of computation in various natural processes. He emphasizes that computation is not limited to computers but is integral to processes in the human brain, the growth of trees, weather patterns, and celestial phenomena. This interdisciplinary perspective has forged fruitful collaborations between theoretical computer science and statistical physics, quantum physics, computational biology, economics, and social sciences.
Although Wigderson’s research is primarily theoretical, he acknowledges the potential practical applications that emerge from fundamental work. He points to the example of Alan Turing, the pioneer of computer science, who wrote a seminal paper without the motivation of practical applications. However, the ideas presented in that paper laid the foundation for the development of computer science as a discipline. Similarly, Wigderson’s work on zero-knowledge interactive proofs, which allow the verification of proof without revealing any additional information, has found unexpected applications in blockchain and other cryptographic systems.
Despite his countless achievements, Wigderson remains humble and driven by curiosity. He expresses enthusiasm for collaborating with postdocs each year and embarking on new projects. Currently, one of his projects focuses on generalizing convex optimization theory to non-Euclidean settings. This extension of the theory has broad implications across mathematics, physics, computer science, and other disciplines.
In conclusion, Avi Wigderson’s recognition as the recipient of the 2023 A.M. Turing Award is a testament to his groundbreaking contributions to the field of computer science. His research has revolutionized our understanding of randomness in computation and has opened new avenues for interdisciplinary collaborations. As he continues to delve into new projects, it is clear that Wigderson’s intellectual leadership will continue to shape the future of theoretical computer science.
