A Survey of Linear and Mixed-Integer Optimization Tutorials

INFORMS Transactions on Education, 2013
As advanced undergraduate and graduate students in optimization begin conducting research, they must base their work on articles found in academic journals. However, there is often a gap between the levels at which a journal article and a textbook are written.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
