}A Circuit node is controllable if a subset of its inputs is able to determine node’s value
}A node implementing the AND logic function is controllable, as the evaluation of any of its inputs to 0 is able to determine node’s value.
}A node implementing the XOR logic function is not controllable, as every input value is needed in order to evaluate node’s value.
