The Tenth International Conference on Parallel Problem Solving from Nature (PPSN X) will be held in Dortmund, Germany on 13-17 September 2008. This meeting will bring together an international community from academia, government, and industry interested in algorithms suggested by the unifying theme of natural computing.
Natural Computing is the study of computational systems that use ideas and get inspiration from natural systems, including biological, ecological, physical, chemical, and social systems. It is a fast growing interdisciplinary field in which a range of techniques and methods are studied for dealing with large, complex, and dynamic problems with various sources of potential uncertainties.
The PPSN conference series started 1990 in Dortmund. Have a look at the history of PPSN.
