Unate function
A unate function is a type of boolean function which has monotonic properties.
They have been studied extensively in switching theory.
A function is said to be positive unate in
if for all possible values of,
Likewise, it is negative unate in if
If for every f is either positive or negative unate in the variable then it is said to be unate. A function is binate if it is not unate.
For example, the logical disjunction function or with boolean values used for true and false is positive unate. Conversely, Exclusive or is non-unate, because the transition from 0 to 1 on input x0 is both positive unate and negative unate, depending on the input value on x1.
Positive unateness can also be considered as passing the same slope and negative unate is passing the opposite slope....
non unate is dependence on more than one input
