These are cheap, simple, generally accurate and relatively robust. Robust and efficient for general linear SDP problems. It promises to be more robust and stable against environmental perturbations. The IBM PC keyboard is very robust and flexible. The Corsair was welcomed as a more robust and versatile alternative. It is very specific, but not very robust. They are robust and agile hunters with excellent eyesight. The posterior median is attractive as a robust estimator. The objective is a more robust evaluation. This is useful for determining if a system is robust. This allowed generation of much more robust and complex code. Success was unpredictable and the fixation not very robust. Piaggio asked D'Ascanio to create a simple, robust and affordable vehicle. Such simplifying assumptions were once necessary for the construction of mathematically robust models. That makes it the most robust of all the PSKs.
