This PALO volume constitutes the Proceedings
of the 19^th Asia Pacific Symposium on Intelligent and Evolutionary
Systems (IES 2015), held in Bangkok, Thailand, November 22-25, 2015. The IES series
of conference is an annual event that was initiated back in 1997 in Canberra,
Australia. IES aims to bring together researchers from countries of the Asian
Pacific Rim, in the fields of intelligent systems and evolutionary computation,
to exchange ideas, present recent results and discuss possible collaborations.
Researchers beyond Asian Pacific Rim countries are also welcome and encouraged
to participate. The theme for IES 2015 is “Transforming Big Data into
Knowledge and Technological Breakthroughs”.

The host organization for IES 2015 is the
School of Information Technology (SIT), King Mongkut’s University of Technology
Thonburi (KMUTT), and it is technically sponsored by the International Neural
Network Society (INNS). IES 2015 is collocated with three other conferences;
namely, The 6th International Conference on Computational Systems-Biology and
Bioinformatics 2015 (CSBio 2015), The 7th International Conference on Advances
in Information Technology 2015 (IAIT 2015) and The 10th International
Conference on e-Business 2015 (iNCEB 2015), as a major part of series of events
to celebrate the SIT 20^th anniversary and the KMUTT 55^th anniversary.
