Some months ago I read an interesting interview with Professor Hans-Paul Schwefel (from the Chair of Systems Analysis (Ls11) - University of Dortmund) at EvoWeb. See here.
The interview has a historic, biographical, and interesting spirit related to Evolutionary Computation.
A small excerpt:
'Why,' he [Professor Schwefel] wonders, 'look for GA variants that provide a similar performance to ES, if Evolution Strategies have already provided such performance for more than twenty years?'
Well, that is a question which I also would like to find an answer! :)
