Re: [R] How to Optimize two functions together in R
Use defaul values initially, to see if you got reasonable results.

I try to use NSGAII function in the mco but I am kind of confusing about the numbers of input and output dimension in the argument. Could you explain a little about this?

Re: [R] How to Optimize two functions together in R
This deals with the multi-objective optimisation.

Try to minimize the sum of those two functions.
