This issue of AIEDAM is the second in
a series of three “mini” special issues on
Evolutionary Design by computers. The papers continue the
theme that began in Vol. 13, No. 3, 1999, of using Evolutionary
Computation for design problems. The first paper by Eby,
Averill, Punch and Goodman provides an excellent overview
of the most recent work at Michigan State University on
this subject. They describe their work on the optimization
of flywheels by an injection island genetic algorithm,
and show the importance of minimizing the computation time
devoted to evaluation for such real-world applications.
