Minimum (conjunctive) The minimum uses the minimum input as its output. This
means the function can only return a high output if all the inputs are high. Such
aggregation is useful for certain KB or UB systems using Eq. (22.5) or even CB
where it is desired that all the inputs be satisfied. Functions such as the product
(TP) have an accumulative effect for any output which is not perfect, so might be
less useful than the min when the dimension is high.
