The Rolf Nevanlinna Prize, known from 2022 as the IMU Abacus Medal,[1] is awarded once every four years at the International Congress of Mathematicians, hosted by the International Mathematical Union (IMU), for outstanding contributions in Mathematical Aspects of Information Sciences including:

  1. All mathematical aspects of computer science, including computational complexity theory, logic of programming languages, analysis of algorithms, cryptography, computer vision, pattern recognition, information processing and modelling of intelligence.
  2. Scientific computing and numerical analysis. Computational aspects of optimization and control theory. Computer algebra.

The prize was established in 1981 by the Executive Committee of the International Mathematical Union and named for the Finnish mathematician Rolf Nevanlinna. It consists of a gold medal and cash prize. The prize is targeted at younger theoretical computer scientists, and only those younger than 40 on January 1 of the award year are eligible.[2] It is awarded along with other IMU prizes including the Fields Medal.[3]


The prize was named to honour the Finnish mathematician Rolf Nevanlinna who had died a year before the prize's creation in 1981. The medal features a profile of Nevanlinna, the text "Rolf Nevanlinna Prize", and very small characters "RH 83" on its obverse. RH refers to Raimo Heino, the medal's designer, and 83 to the year of first minting. On the reverse, two figures related to the University of Helsinki, the prize sponsor, are engraved. The rim bears the name of the prizewinner.[4]

Alexander Soifer, president of the World Federation of National Mathematics Competitions, complained about the prize's honouring of Nevanlinna, as he was a supporter of Hitler and had acted as a representative for the Finnish Volunteer Battalion of the Waffen-SS during World War II. Soifer discussed Nevanlinna's wartime activities in a 2015 book, and forwarded his personal and his organization’s requests to the Executive Committee of IMU to change the Prize's name.[5][6] In July 2018, the 18th General Assembly of the IMU decided to remove the name of Rolf Nevanlinna from the prize.[7] It was later announced that the prize would be named the IMU Abacus Medal.[1]


Year Laureate Reasons
1982 Robert Tarjan "Received the first Nevanlinna Prize for outstanding contributions to mathematical aspects of information science. "Pure mathematics enjoys the luxury of studying its constructions, whether finite or infinite, in complete independence of all questions of efficiency." explained Jacob Schwartz, who spoke on Tarjan's work. "By contrast, theoretical computer science must ultimately concern itself with computing engines which operate with limited speed and data storage, and therefore must take efficiency as one of its central concerns. Two closely related activities, algorithm design and algorithm analysis, grow out of this inevitable concern."[8]
1986 Leslie Valiant "Valiant has contributed in a decisive way to the growth of almost every branch of the fast growing young tree of theoretical computer science, his theory of counting problems being perhaps his most important and mature work."[9]
1990 Alexander Razborov
1994 Avi Wigderson
1998 Peter Shor For his outstanding work on quantum computation and in particular for deriving the Shor's algorithm.
2002 Madhu Sudan
2006 Jon Kleinberg
2010 Daniel Spielman[10]
2014 Subhash Khot[11] "For his prescient definition of the “Unique Games” problem, and leading the effort to understand its complexity and its pivotal role in the study of efficient approximation of optimization problems; his work has led to breakthroughs in algorithmic design and approximation hardness, and to new exciting interactions between computational complexity, analysis and geometry."[12]
2018 Constantinos Daskalakis[13] "For transforming our understanding of the computational complexity of fundamental problems in markets, auctions, equilibria, and other economic structures. His work provides both efficient algorithms and limits on what can be performed efficiently in these domains."[14]
