Machine learning is one of the key application fields of Genetic algorithms. A<br />

survey of the recent literature [14] on GA reveals that a major area of its<br />

applications is concerned with artificial neural nets. It can work with neural<br />

nets in three basic ways [15]. First it can adjust the parameters, such as<br />

weights <strong>and</strong> non-linearity of a neural net, when the training instances are
