For example, the inputs can be design parameters of a motor while the output can be the power consumption.
Other inputs can be business choices with the output being obtained profit.
or describing the configuration of a physical system with the output being its energy.
An optimization problem can be represented in the following way Typically, A is some subset of the Euclidean space Rn, often specified by a set of constraints, equalities or inequalities that the members of A have to satisfy.
Maximization can be reduced to minimization by multiplying the function by minus one.
