> Does R have packages for such multi-objectives optimization problems ?
The "rgenoud" (R-GENetic Optimization Using Derivatives) package
allows for multiple object optimization problems. See the "lexical"
option which searches for the Pareto front. The package is written
for NP-hard problems (b
Regarding multi-object optimization, I just got 0 hits from

too difficult to write a wrapper function to blend other functions
however you would like, then use "optim"

Then you have two choices :
1) balance the two objectives with weights, according to the i
