I get N=178 for that. Is that what you get?

Yeah, I guessed 27 log 2 was around 4.5 so I got 177.

I should mention that most of Goldberg's research is in GAs using only a selection operator and a recombination operator, no mutation. This despite publishing papers (see the "Ready to Rumble" series) that show mutation is the more efficient operator in some broad classes of problems.

Since Weasel is really a (1,n)-ES, not a selectorecombinative GA, that population sizing heuristic might not be completely appropriate. But I don't know of other work with as firm a footing.
