ICGAs (International Conferences on Genetic Algorithms) were biannual conferences that started in 1985 in Pittsburgh, PA, USA. The 7th and last edition was held in East Lansing, Michigan, USA: the conference decided to merge with the Genetic Programming conference and to become the Genetic and Evolutionary Computation COnference, aka GECCO.

All references to ICGA papers can be found on the associated DBLP page. The "Contents" link of each volume provides a table of contents. The proceedings were published by Morgan Kauffman and have not been digitally archived. Copies are available from various university libraries and other sources.
