A relation R is defined on ordered pairs of integers as (x, y) R (u, v) if x < u and y > v. Then R is
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: A. Neither a partial order nor an equivalence relation
Explanation
Because the inequalities are strict, (x, y) R (x, y) never holds, so R is not reflexive. A partial order and an equivalence relation both need reflexivity.More Discrete Structures and Optimization questions
