In case anyone is interested, my book, Essentials of Metaheuristics, First Edition, IS NOW AVAILABLE IN PAPERBACK. To get the print edition go to: http://cs.gmu.edu/~sean/book/metaheuristics It's available from Lulu.com now, and sometime in the near future will be available from Amazon.com and Amazon.co.uk. (Get it from Lulu anyway, it's cheaper). Thanks everyone, and I do not expect to need to send out another message again. Sean Luke Department of Computer Science George Mason University
