hello, in the task of finding the optimal phase covariant cloning machine, i have to maximize two functions of six variables :f1=a.C+b.D and f2=a.B+c.D , they are many constraints, but I've already used them to get to those expressions in the first place, the variables are real scalars and vary between -1 and 1. of course I'm not searching for numerical values for the six variables, in fact I've already got a transformation (set of variables) which i know is optimal, all I'm looking for is a way to prove that it is actually optimal and i know there can be others sets of variables which provide optimality.
