“…Similarly, for wire antennas [69,70,139], the representational scheme is based on the way a draftsman might draw an antenna (either on paper or using a two-or three-dimensional graphical interface for engineering drawings). In particular, the function set consists of one key function that inserts a straight segment of metal wire with a specified length (or no wire) and at a specified angle starting at a specified point, using a turtle [128,139].…”

“…The Numerical Electromagnetics Code (NEC-2) is a MoM-based, user-oriented computer code for the analysis of the electromagnetic response of wire antennas and other metallic structures (Lohn et al, 2005). It is built around the numerical solution of the integral equations for the currents induced on the structure.…”

“…First of all, the gain is the far-field parameter of interest and, second, this prevents from considering superdirective antennas, both during the evolution and as final solution, which is even worse. NEC has been successfully used to model a wide range of antennas, with high accuracy (Burke & Poggio, 1976a, 1976b, 1981Deadrick et al, 1977) and is now considered as one of the reference electromagnetic software (Lohn et al, 2005;Linden & Altshuler, 1996. However, since SED is by no means linked, or tailored, to NEC, a different, and most effective, EM software could be used, to reduce the total computational time, further improving the accuracy of the simulation.…”

“…Given a set of functions and terminals and an initial population of randomly generated syntax trees (representing programs), the programs are evolved through genetic recombination and natural selection. GP has been applied to many different problems; from classical tasks, such as function fitting or pattern recognition, to non-trivial tasks that are competitive with significant human endeavours such as designing electrical circuits [25] or antennas [26].…”

“…Similar to other applications of GP [24][25][26] for solving optimization problems, we use four basic operators: addition, subtraction, multiplication, and division for creating a CDR. Furthermore, we employ a well-known Automatically Defined Function (ADF) (proposed by Koza [28]).…”
