(a) linear function

(b) weighted sum function

(c) logarithmic function

(d) linear logarithmic function

I had been asked this question in a national level competition.

Question is from Techniques in chapter Cognitive Techniques of Cognitive Radio

Answer 1

Right option is (d) linear logarithmic function

The best I can explain: Cobb Douglas function is otherwise called linear logarithmic function. It is an advanced version of weighted sum approach. The result is shaped by the logarithmic function. The logarithmic function adds convexity to the optimisation curve.
