The present book includes a set of selected extended papers from the fifth International Joint
Conference on Computational Intelligence (IJCCI 2013) held in Vilamoura Algarve Portugal
from 20 to 22 September 2013. The conference was composed by three co-located conferences: The
International Conference on Evolutionary Computation Theory and Applications (ECTA) the
International Conference on Fuzzy Computation Theory and Applications (FCTA) and the
International Conference on Neural Computation Theory and Applications (NCTA). Recent
progresses in scientific developments and applications in these three areas are reported in
this book. IJCCI received 111 submissions from 30 countries in all continents. After a double
blind paper review performed by the Program Committee only 24 submissions were accepted as
full papers and thus selected for oral presentation leading to a full paper acceptance ratio
of 22%. Additional papers were accepted as short papers and posters. A further selection was
made after the Conference based also on the assessment of presentation quality and audience
interest so that this book includes the extended and revised versions of the very best papers
of IJCCI 2013. Commitment to high quality standards is a major concern of IJCCI that will be
maintained in the next editions considering not only the stringent paper acceptance ratios but
also the quality of the program committee keynote lectures participation level and logistics.
