I'm not very sure, but in this line wouldn't it be safer to set the minimum to 1*nbObjectives ? Even though the nOffspring shouldn't be less than 1 to begin with I guess.

This is executed for each objective, so you just want at least one offspring per objective. Which means the total will be >= nbObjectives. I believe this is the correct & expected behavior!
