time: t1 t2 t3 t4 t5 t6

L1: 1 3 4 5 6 1

L2: 1 1 1 1 1 1

L3: 2 1 4 5 6 7

...

Ln: 2 1 4 5 6 7

I would like to distribute the loads over the three distribution lines in order to achieve the best distribution possible, that is, minimize the difference between phase A,B,C.

Has anybody a hint which approach is best and better and example application?

To me it is a optimisation problem, I may solve with something like Newton or so. But I cannot find the solution. The problem is, that in contrast to the following example, I have vector for x and not values:

min(f(x))=x2+10(x-x^2) ...

My x in there are vectors again

Thanks a lot.
