“…In fact, there has been a constant demand on IT professionals for improved methodologies, design, and applications. Accordingly, the researchers are responding to this demand through computational intelligence, particularly focusing on neural networks (Haykin, 1994;Wang & Takefuji, 1993), genetic algorithms (Davis, 1987;Deb, 2001;Goldberg, 1989), evolutionary programming (Diego & Duc Truong, 2007;Konar & Jain, 2001), artificial immune systems (Dasgupta, 1980;De Castro & Timmis, 2002), and fuzzy systems (Zadeh, 1965;Zimmermann, 1999).…”
