“…It is worth mentioning here that, even though power tilt and azimuth are actually real-valued parameters, they are usually discretized into a rather small set of values in order to reduce the complexity of the optimization problem. This is the approach used in Altman et al (2002a,b), Cahon et al (2006), Jamaa et al (2004aJamaa et al ( ,b, 2006, Jedidi et al (2004), Meunier et al (2000), Picard et al (2005), Reininger et al (1999), Talbi et al (2007), Talbi and Meunier (2006), Zimmermann et al (2000Zimmermann et al ( , 2003a. The main advantage of this encoding scheme is that EAs are put to work on real solutions so therefore problem-domain specific knowledge can be easily included in the search.…”
