In 2011 the ANNIE Conference series was concluded and a new series began under a broader focus, entitled Complex Adaptive Systems. The conference and publication structure was designed to enable a different theme and location each year. The first year of the conference was a great success with over 100 participants from around the world that met in Chicago, Illinois. Since then the conference has moved to Washington D.C. in 2012, Baltimore, MD in 2013, Philadelphia, PA in 2014, San Jose, CA in 2015, Los Angeles, CA in 2016, and Chicago, IL in 2017 and has continued to bring together experts in academia, industry and government to push the boundaries of knowledge of Complex Systems to the next level.
From 1991 – 2010 the ANNIE Conferences provided an international forum for researchers who were interested in engineering applications of Fuzzy Logic and Systems, Neural Networks and Evolutionary Programming in St. Louis, Missouri, USA.
