Then you have two choices :
1) balance the two objectives with weights, according to the importance
you give to each one
2) get a list of non-dominated solutions (a "Pareto front")
Does R have packages for such multi-objectives optimization problems ?
Moreover, does it have a package for "difficult" (i.e. NP-hard) problems ?
