Workshop Announcement and Call for Participation

The 2nd Grammatical Evolution Workshop (GEWS 2003)

a Workshop of

The 2003 Genetic and Evolutionary Computation Conference (GECCO-2003)

July 12-16, 2003, Chicago, USA

Following on from the success of the first Grammatical Evolution Workshop (GEWS 2002) held at GECCO 2002, the 2nd Grammatical Evolution Workshop will be held at GECCO 2003.

Grammatical Evolution (GE) is an automatic programming system that can evolve programs in an arbitrary language from a binary string. GE adopts a genotype-phenotype mapping process taking as input a grammar that describes the syntax of the evolved program. In addition to the grammar, the search algorithm (the standard has been a variable-length genetic algorithm) is also a 'plug-in' component of the system.

The workshop will address all aspects of GE including foundations, extensions, analysis and applications.
