What crops are constrained by seed limitations? To what extent?
What about preferences?
What are the minimum acreages for each crop?

Note that despite the complexity of the problem, MATLAB solves it almost
instantaneously. It seems the farmer should bet the farm on crop number 6.
We suggest you alter the expense and/or the storage limit in the problem and
see what effect that has on the answer.
The 360 ˚ Pendulum
Normally we think of a pendulum as a weight suspended by a flexible string
or cable, so that it may swing back and forth. Another type of pendulum
consists of a weight attached by a light (but inflexible) rod to an axle, so that
