EuroGP - the European Conference on Genetic Programming - has been held every year since 1998. All EuroGP papers are available on line as part of Springer's LNCS series. The original annual Genetic Programming conference ran for three years (1996-1998) before combining in 1999 with the International Conference on Genetic Algorithms (ICGA) to form GECCO. 98% of GECCO papers are available on-line. The Michigan-based Genetic Programming Theory and Practice workshop (O'Reilly, Yu, Riolo, and Worzel, 2004; Riolo and Worzel, 2003; Riolo, Soule, and Worzel, 2007a; ?) has recently published its fifth proceedings (Riolo, Soule, and Worzel, 2007b). Other EC conferences, such as CEC, PPSN, Evolution Artificielle and WSC, also regularly contain GP papers.
