Illinois Genetic Algorithms Laboratory

I saw a post on the genetic programming list, I think, on a "new" kind of optimization algorithm called, get this, invasive weed optmization. I know nothing about the crux of what's being done or claimed for IWO, but it seems to me we've seen this sort of thing before.  It's almost a recipe:

1. Take a GA or some other form of EC
2. Twiddle with the operators a bit
3. Give it a new name
4. Declare yourself a pioneer of our computational age. 

I suppose I should read up on what IWO really is before publicly displaying my skepticism, but I haven't gotten too excited by other recent incarnations (particles, swarms, insects, etc.) of population-oriented GEC variants.  At least not enough to give them status separate from genetic and evolutionary computation broadly conceived.
