Sergio García Introduction to convex optimization I June 2018 11 / 21. Correct! Convex Optimization Problems Definition An optimization problem is convex if its objective is a convex function, the inequality constraints fj are convex, and the equality constraints hj are affine minimize x f0(x) (Convex function) s.t. Convex optimization problems arise frequently in many different fields. This book should also prepare the reader for working in areas beyond convex optimization, e.g., nonconvex optimization and geodesic convex optimization, which are currently in their formative years. >> Authors: Elad Hazan. /Resources 26 0 R endobj Optimization terms used in the design and analysis introduction to convex optimization communication systems and signal processing and Communications, CambridgeUniversityPress,.!
