“…These investigations sparked a host of attempts to apply aspects of immunology to a wider range of engineering problems, and the reader is referred to the International Conference on Artificial Immune Systems (ICARIS) for a comprehensive collection of papers [7,8,9,10,11,12]. Over recent years there have been a number of review papers written on AIS with the first being [13] followed by a series of others that either review AIS in general, for example, [14,15,16,17,18], or more specific aspects of AIS such as data mining [19], network security [20], applications of AIS [21], theoretical aspects [22] and modelling in AIS [23].…”
