Optimization Criteria

There are a series of target criteria for the optimization of one or several outputs that are described in the following table.

Criterion

Value

Meaning

Minimize/Maximize

None

Optimization to minimum/maximum value without further restrictions.

Hard Lower and/or Upper Bound

Optimization to minimum/maximum value with additional lower and/or upper limit.

Target

 

Optimization to target value – the amount of deviation from target is minimized.

Bound

 

Optimization with limits.

Hard Lower and/o Upper Bound

Specifies fixed lower and/or upper limits for the optimizer.

If these limits are overrun/underrun, the optimization concludes without a result. In case of an optimization of the type "single criteria at OPs" the "weak upper/lower bound" criterion is used for further optimization.

Weak Upper/
Lower Bound

A weakened form of "Hard ... Bound".

Minimizing/maximizing up to a threshold, all values below or above it are not optimized any further.
