Imre Pólik is an Optimization Solver Developer for SAS/OR, working on the linear and mixed-integer optimization solvers. He earned his M.S. in Mathematics from Eötvös University in Budapest, Hungary, and his Ph.D. in Mathematics from McMaster University, Hamilton, Ontario, Canada. He has worked for SAS since 2010, following a couple of years as a visiting assistant professor at Lehigh University. Currently he is managing the Optimization and Network Algorithms team within the Analytics R&D Division.
In 2013, Rick Wicklin blogged about visualizing matrices as heat maps using SAS/IML. That post reminded me that we had done a similar thing for the coefficient matrices in our optimization problems. In particular, we have developed some SAS macros to visualize the input data sets for the OPTLP (linear
Peg solitaire I love puzzles; I have a few of them in my office. I regularly use them at interviews: I ask the candidate either to solve a puzzle or to devise a (clever) mathematical algorithm that solves it. I'm sure a lot of readers are familiar with the standard
The 2014 INFORMS Annual Conference in San Francisco was quite a success. Record attendance, diverse program, great city, lovely weather: who can ask for more? SAS and, in particular, SAS/OR was well-represented with a number of talks in all areas of operations research. Here is a somewhat arbitrary selection, please click
