David William Matula (born 1937) [1] is an American mathematician and computer scientist known for his research on graph theory, graph algorithms, computer arithmetic, and algorithm engineering. He is a professor emeritus at Southern Methodist University, where he formerly held the Cruse C. and Marjorie F. Calahan Centennial Chair in Engineering. [2]
Matula was an undergraduate at Washington University in St. Louis, [2] graduating in 1959. [3] He completed his Ph.D. in 1966 at the University of California, Berkeley, with the dissertation Games of Sequence Prediction supervised by David Blackwell. [4]
After completing his Ph.D., he returned to Washington University in St. Louis as a faculty member. He joined the Southern Methodist University faculty in 1974 as chair of the Computer Science and Engineering Department, [2] was named to the Cruse C. and Marjorie F. Calahan Centennial Chair in Engineering in 2016, [3] and retired in 2018. [2]
Matula is the coauthor, with Peter Kornerup, of the book Finite Precision Number Systems and Arithmetic (Encyclopedia of Mathematics and its Applications 133, Cambridge University Press, 2010). [5]
Discrete mathematics is the study of mathematical structures that can be considered "discrete" rather than "continuous". Objects studied in discrete mathematics include integers, graphs, and statements in logic. By contrast, discrete mathematics excludes topics in "continuous mathematics" such as real numbers, calculus or Euclidean geometry. Discrete objects can often be enumerated by integers; more formally, discrete mathematics has been characterized as the branch of mathematics dealing with countable sets. However, there is no exact definition of the term "discrete mathematics".
In computing, floating-point arithmetic (FP) is arithmetic that represents subsets of real numbers using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. Numbers of this form are called floating-point numbers. For example, 12.345 is a floating-point number in base ten with five digits of precision:
Numerical analysis is the study of algorithms that use numerical approximation for the problems of mathematical analysis. It is the study of numerical methods that attempt to find approximate solutions of problems rather than the exact ones. Numerical analysis finds application in all fields of engineering and the physical sciences, and in the 21st century also the life and social sciences, medicine, business and even the arts. Current growth in computing power has enabled the use of more complex numerical analysis, providing detailed and realistic mathematical models in science and engineering. Examples of numerical analysis include: ordinary differential equations as found in celestial mechanics, numerical linear algebra in data analysis, and stochastic differential equations and Markov chains for simulating living cells in medicine and biology.
A computer algebra system (CAS) or symbolic algebra system (SAS) is any mathematical software with the ability to manipulate mathematical expressions in a way similar to the traditional manual computations of mathematicians and scientists. The development of the computer algebra systems in the second half of the 20th century is part of the discipline of "computer algebra" or "symbolic computation", which has spurred work in algorithms over mathematical objects such as polynomials.
David Volfovich Chudnovsky and Gregory Volfovich Chudnovsky are Ukrainian-born American mathematicians and engineers known for their world-record mathematical calculations and developing the Chudnovsky algorithm used to calculate the digits of π with extreme precision.
David A. Bader is a Distinguished Professor and Director of the Institute for Data Science at the New Jersey Institute of Technology. Previously, he served as the Chair of the Georgia Institute of Technology School of Computational Science & Engineering, where he was also a founding professor, and the executive director of High-Performance Computing at the Georgia Tech College of Computing. In 2007, he was named the first director of the Sony Toshiba IBM Center of Competence for the Cell Processor at Georgia Tech.
Eric "Rick" C. R. Hehner is a Canadian computer scientist. He was born in Ottawa. He studied mathematics and physics at Carleton University, graduating with a Bachelor of Science (B.Sc.) in 1969. He studied computer science at the University of Toronto, graduating with a Master of Science (M.Sc.) in 1970, and a Doctor of Philosophy (Ph.D.) in 1974. He then joined the faculty there, becoming a full professor in 1983. He became the Bell University Chair in software engineering in 2001, and retired in 2012.

He has published over 200 scientific papers and is listed as an ISI highly cited researcher.
Jorge Stolfi is a full professor of computer science at the State University of Campinas, working in computer vision, image processing, splines and other function approximation methods, graph theory, computational geometry and several other fields. According to the ISI Web Of Science, as of 2010 he was the most highly cited computer scientist in Brazil. Outside of academia, Stolfi has accrued an online following due to his skepticism and comments on Bitcoin.

Giuseppe Francesco (Pino) Italiano is an Italian computer scientist. He is a professor of computer science at LUISS University in Rome. He is known for his work in graph algorithms, data structures and algorithm engineering.
In computing, tapered floating point (TFP) is a format similar to floating point, but with variable-sized entries for the significand and exponent instead of the fixed-length entries found in normal floating-point formats. In addition to this, tapered floating-point formats provide a fixed-size pointer entry indicating the number of digits in the exponent entry. The number of digits of the significand entry results from the difference of the fixed total length minus the length of the exponent and pointer entries.
