It is self-evident that multiple criteria lead to conflicting situations unless they are independent, and complete inde- pendence is quite uncommon in reality. We illustrate by means of a simple example: Driving a car from point A to point B takes time and consumes gasoline. Clearly, everybody wants to reach B as quickly as possible and the gas- oline costs should be minimal. Every car requires more gasoline to drive faster and so we are dealing with two naive pseudo-optima: (i) the shortest time to reach B from A and (ii) the most economic speed to drive from A to B, and needless to say these two optima will be different.
Optimization of multiple criteria: Pareto efficiency and fast heuristics should be more popular than they are
