TLDR
The procedure explained can be used to provide good initial designs for use with iterative search techniques to reduce searching time and is highly desirable in connection with increasing the effectiveness of the optimal design procedure.Abstract:
A novel method for the optimal design of the electromagnetic devices is presented The method utilizes artificial neural networks (ANNs) in a design environment which encompasses numerical computations and expert's input for generating a variety of ANN training data Results of two implementation examples are provided The optimal design is obtained quickly (in a matter of milliseconds) once the ANNs are trained with a variety of geometrical topologies The procedure explained can be used to provide good initial designs for use with iterative search techniques (currently used) to reduce searching time This aspect is highly desirable in connection with increasing the effectiveness of the optimal design procedure >read more

Artificial neural networks in the solution of inverse electromagnetic field problems
TL;DR: It is shown that artificial neural networks have a role to play in a limited domain of applications and while it is ineffective to train networks to cover a broad class of devices, it is indeed possible to develop well-trained networks that function effectively over a narrow range of performance of a particular class of device.

A Two-Level Genetic Algorithm for Electromagnetic Optimization
TL;DR: A two-level genetic algorithm (2LGA) for electromagnetic optimization that employs the global convergence properties of the genetic algorithm, where acceleration of the optimization results from the fast computations of the coarse model (low level) and where accuracy is guaranteed by using a limited number of fine model evaluations.

TL;DR: The more the authors study the information processing aspects of the mind, the more perplexed and impressed they become, and it will be a very long time before they understand these processes sufficiently to reproduce them.
