“This unique book gives a smooth introduction
to optimization for electrical engineering students and professionals.
It focuses on electrical applications rather
than on lengthy mathematical proofs. The
addressed applications included design of microwave filters and antennas, the
design of photonic devices, analog filters, digital filters, image recognition,
and training of neural networks. The
book contains one full chapter which introduces the theory of adjoint sensitivities in a smooth way. A general overview
of the most practical global optimization techniques is also presented”
