The current thesis examines evolutionary techniques for the training of Artificial Neural Networks (ANN). The term evolutionary technique refers to a subset of post-heuristic techniques. Evolutionary algorithms include techniques which try to simulate behaviors of populations found in nature, such as the process of evolution of species , the movement of birds from one place to another , finding food in fish-swarm , and more . The conventional way of training an ANN is using the back-propagation algorithm ( BP - Back Propagation). In this work the algorithm BP is compared with 3 evolutionary techniques the Genetic Algorithm ( GA ), the PSO algorithm and a hybrid approach them called HGAPSO . For efficient comparison of these four algorithms we implemented a software which applies the four techniques on data sets . The data sets that were used were recovered from the UCI Machine Learning Repository ( https://archive.ics.uci.edu/ml/datasets.html). The training data properly transformed, in an equivalent form so as to be used by the software.
