The article "Bad semidefinite programs: They all look the same" by Professor Gabor Pataki is chosen as a featured article by SIAM Journal on OptimizationMarch 21, 2017
Semidefinite programs (SDPs) are one of the most important optimization problems today: they are applicable in engineering, economics, and many other fields and can be efficiently solved. At the same time, SDPs often exhibit certain pathological behaviors. This paper gives a very simple characterization of these pathological behaviors.
SIAM Journal on Optimization is one of the premier journals on optimization: it publishes more than 100 articles a year, and chooses one featured article approximately every 6 months.
