Weighted Sum Optimization in R (Maximization)
...owing function in R;
MAXIMIZE
function = w1*R1 + w2*R2 + w3*R3 + w4*R4
Where constraints are,
w1 + w2 + w3 + w4 = 1 and 0 <= w1, w2, w3, w4 <= 1
Does optim in R can do this optimization? If so, could anyone show me
how to use 'optim()' in R?
Thank you in advance and regards,
Myung
