The present book includes a set of selected extended papers from the sixth International Joint
Conference on Computational Intelligence (IJCCI 2014) held in Rome Italy from 22 to 24
October 2014. 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 210 submissions from 51 countries in all continents. After a double blind paper
review performed by the Program Committee 15% were accepted as full papers and thus selected
for oral presentation. 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 2014. 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.
