Richard Robert Weber (born 25 February 1953) is a mathematician working in operational research. [1] [2] He is Emeritus Churchill Professor of Mathematics for Operational Research in the Statistical Laboratory, University of Cambridge.
Weber was educated at Walnut Hills High School, Solihull School and Downing College, Cambridge. He graduated in 1974, and completed his PhD in 1980 under the supervision of Peter Nash. [3] He has been on the faculty of the University of Cambridge since 1978, and a fellow of Queens' College since 1977 where he has been Vice President from 1996–2007 and again from 2018–2020. He was appointed Churchill Professor in 1994, and he became Emeritus Churchill Professor on retirement in 2017. He was Director of the Statistical Laboratory from 1999 to 2009, and is a trustee of the Rollo Davidson Trust. [4]
He works on the mathematics of large complex systems subject to uncertainty. He has made contributions to stochastic scheduling, Markov decision processes, queueing theory, the probabilistic analysis of algorithms, the theory of communications pricing and control, and rendezvous search.
Weber and his co-authors were awarded the 2007 INFORMS prize for their paper on the online bin packing algorithm. [5]
Ross John Anderson was a British researcher, author, and industry consultant in security engineering. He was Professor of Security Engineering at the Department of Computer Science and Technology, University of Cambridge where he was part of the University's security group.
The rendezvous dilemma is a logical dilemma, typically formulated in this way:
Ronald Lewis Graham was an American mathematician credited by the American Mathematical Society as "one of the principal architects of the rapid development worldwide of discrete mathematics in recent years". He was president of both the American Mathematical Society and the Mathematical Association of America, and his honors included the Leroy P. Steele Prize for lifetime achievement and election to the National Academy of Sciences.
The bin packing problem is an optimization problem, in which items of different sizes must be packed into a finite number of bins or containers, each of a fixed given capacity, in a way that minimizes the number of bins used. The problem has many applications, such as filling up containers, loading trucks with weight capacity constraints, creating file backups in media, splitting a network prefix into multiple subnets, and technology mapping in FPGA semiconductor chip design.
A unit fraction is a positive fraction with one as its numerator, 1/n. It is the multiplicative inverse (reciprocal) of the denominator of the fraction, which must be a positive natural number. Examples are 1/1, 1/2, 1/3, 1/4, 1/5, etc. When an object is divided into equal parts, each part is a unit fraction of the whole.
Edward Grady "Ed" Coffman Jr. is a computer scientist. He began his career as a systems programmer at the System Development Corporation (SDC) during the period 1958–65. His PhD in engineering at UCLA in 1966 was followed by a series of positions at Princeton University (1966–69), The Pennsylvania State University (1970–76), Columbia University (1976–77), and the University of California, Santa Barbara (1977–79). In 1979, he joined the Mathematics Center at Bell Laboratories where he stayed until his retirement as a Distinguished Member of Technical Staff 20 years later. After a one-year stint at the New Jersey Institute of Technology, he returned to Columbia University in 2000 with appointments in Computer Science, Electrical Engineering, and Industrial Engineering and Operations Research. He retired from teaching in 2008 and is now a professor emeritus still engaged in research and professional activities.
Peter Whittle was a mathematician and statistician from New Zealand, working in the fields of stochastic nets, optimal control, time series analysis, stochastic optimisation and stochastic dynamics. From 1967 to 1994, he was the Churchill Professor of Mathematics for Operational Research at the University of Cambridge.
David George Kendall FRS was an English statistician and mathematician, known for his work on probability, statistical shape analysis, ley lines and queueing theory. He spent most of his academic life in the University of Oxford (1946–1962) and the University of Cambridge (1962–1985). He worked with M. S. Bartlett during World War II, and visited Princeton University after the war.
The Rollo Davidson Prize is a prize awarded annually to early-career probabilists by the Rollo Davidson trustees. It is named after English mathematician Rollo Davidson (1944–1970).
Geoffrey Richard GrimmettOLY is an English mathematician known for his work on the mathematics of random systems arising in probability theory and statistical mechanics, especially percolation theory and the contact process. He is the Professor of Mathematical Statistics in the Statistical Laboratory, University of Cambridge, and was the Master of Downing College, Cambridge, from 2013 to 2018.
James Ritchie Norris is a mathematician working in probability theory and stochastic analysis. He is the Professor of Stochastic Analysis in the Statistical Laboratory, University of Cambridge.
Rollo Davidson was a probabilist, alpinist, and Fellow-elect of Churchill College, Cambridge, who died aged 25 on Piz Bernina. He is known for his work on semigroups, stochastic geometry, and stochastic analysis, and for the Rollo Davidson Prize, given in his name to early-career probabilists.
