"A Boolean function can have a variety of properties: • Constant: Is always true or always false regardless of its arguments. • Monotone: for every combination of argument values, changing an argument from false to true can only cause the output to switch from false to true and not from true to false. A function is said to be unate in a certain variable if it is monotone with respect to changes in that variable. " - Boolean function of degree n
