I was invited to join the Organizing Committee of the First International Conference on Complex
Sciences: Theory and Applications (Complex 2009) as its ninth member. At that moment eight
distinguished colleagues General Co-chairs Eugene Stanley and Gaoxi Xiao Technical Co-chairs
János Kertész and Bing-Hong Wang Local Co-chairs Hengshan Wang and Hong-An Che Publicity Team
Shi Xiao and Yubo Wang had spent hundreds of hours pushing the conference half way to its
birth. Ever since then I have been amazed to see hundreds of papers flooding in reviewed and
commented on by the TPC members. Finally more than 200 contributions were - lected for the
proceedings currently in your hands. They include about 200 papers from the main conference
(selected from more than 320 submissions) and about 33 papers from the five collated workshops:
Complexity Theory of Art and Music (COART) Causality in Complex Systems (ComplexCCS) Complex
Engineering Networks (ComplexEN) Modeling and Analysis of Human Dynamics (MANDYN) Social
Physics and its Applications (SPA) Complex sciences are expanding their colonies at such a
dazzling speed that it - comes literally impossible for any conference to cover all the
frontiers.
