Background
Paul Tseng was born September 21, 1959 in Hsinchu, Taiwan.
engineer mathematician computer scientist
Paul Tseng was born September 21, 1959 in Hsinchu, Taiwan.
From Queen"s University in 1981 and his Doctor of Philosophy from Massachusetts Institute of Technology in 1986.
Tseng was recognized by his peers to be one of the leading optimization researchers of his generation. Paul Tseng went missing while kayaking in the Yangtze River in the Yunnan province of China and is presumed dead. In December 1970, Tseng"s family moved to Vancouver, Canada.
Tseng received his Bachelor of Science
In 1990 Tseng moved to the University of Washington"s Department of Mathematics. Tseng has conducted research primarily in continuous optimization and secondarily in discrete optimization and distributed computation.
Tseng made many contributions to mathematical optimization, publishing many articles and helping to develop quality software that has been widely used. Tseng"s research subjects include:
Efficient algorithms for structured convex programs and network flow problems,
Complexity analysis of interior point methods for linear programming,
Parallel and distributed computing,
Error bounds and convergence analysis of iterative algorithms for optimization problems and variational inequalities,
Interior point methods and semidefinite relaxations for hard quadratic and matrix optimization problems, and
Applications of large scale optimization techniques in signal processing and machine learning.
In his research, Tseng gave a new proof for the sharpest complexity result for path-following interior-point methods for linear programming.
Furthermore, together with Tom Luo, he resolved a long-standing open question on the convergence of matrix splitting algorithms for linear complementarity problems and affine variational inequalities. Tseng was the first to establish the convergence of the affine scaling algorithm for linear programming in the presence of degeneracy. Tseng has coauthored (with his Doctor of Philosophy advisor, Dimitri Bertsekas) a publicly available network optimization program, called RELAX, which has been widely used in industry and academia for research purposes.
This software has been used by statisticians like Paul R. Rosenbaum and Donald Rubin in their work on propensity score matching.
Tseng"s software for matching has similarly been used in nonparametric statistics to implement exact tests. Tseng has also developed a program called ERELAXG, for network optimization problems with gains.
In 2010 conferences in his honor were held at the University of Washington and at Fudan University in Shanghai. Tseng"s personal web page can be accessed in the exact state it was at the time of his disappearance, and contains many of his writings.
Paul Tseng was an ardent bicyclist, kayaker and backpacker.
He took many adventurous trips, including kayak tours along the Mekong, the Danube, the Nile and the Amazon. On August 13, 2009, Paul Tseng went missing while kayaking in the Yantze river near Lijiang, in Yunnan province of China and is now presumed dead.
