We want to determine the IQ of an SDG robot.
We subdivide the IQ into sub-IQs for subactivities.

Buying IQ:
How good is the robot at making buying decisions?

The robot is offered a set of derivatives to buy.
Half of them are too cheap (CHEAP) and half too expensive (EXP).
The robot buys set BUY of derivatives.
BuyingIQ = intersect(BUY,CHEAP) - 2 * intersect(BUY,EXP)

Offering IQ:
What is the quality of the derivatives offered by the robot?

Controlled Offering
The robot is asked to create derivatives using relations from a set REL.
The robot creates a set S of derivatives.
The robot should only offer profitable derivatives and they
should not be too expensive.
OfferingIQ = 
SUM over all derivatives in S:
if price > break-even-price then 1 - (price - break-even-price) else 0

Uncontrolled Offering
Robot can choose any relations.

RawMaterial IQ:
What is the quality of the raw material created by the robot?
The raw material should be symmetric and use the worst weights.

Finishing IQ:
What is the quality of the assignments?

RobotIQ = BuyingIQ + OfferingIQ + RawMaterialIQ + FinishingIQ
