An approach to evolutionary distributed optimisation of multilayer perceptrons (MLP) using REST and language Perl has been done. In these experiments, a master-slave based evolutionary algorithm (EA) has been implemented, where slave processes evaluate the costly fitness function (training a MLP to solve a classification problem). Obtained results show that the parallel version of the developed programs obtains simila","authors_text":"A.M. Mora, G. Romero, J.J. Merelo, J.L.J. Laredo, M.G. Arenas, P.A.
