... We discuss the idea of a "fitness landscape" for interferometric arrays, where a fitness function is defined in terms of the success of the array, and the coordinates of the space are design parameters such as numbers and sizes of telescopes, baseline length and wavelength coverage. ... Although the method of solution of the these two design problems is different, in one case evolutionary and in the other (hopefully) deliberate, the nature of the problem is similar in the two cases. ...
