Let P (x) and Q(x) be two predicates and suppose D is the the domain of
For the statement forms in each pair, determine whether they have the same truth value for every choice of p(x), Q(x) and D, or not.
∀x ∈ D, (P (x) ∧ Q(x)), and (∀x ∈ D, P (x)) ∧ (∀x ∈ D, Q(x))
∀x ∈ D, (P (x) ∨ Q(x)), and (∀x ∈ D, P (x)) ∨ (∀x ∈ D, Q(x))
Let p and q be two propositions. Consider the following two formulae in prepositional
logic.
S, : (-p A (p v q)) → p
S: q→(-pA (p v q))
V.
Which one of the following choices is correct?
(a) Neither S, nor S, is a tautology.
(b) Both S, and S, are tautologies.
(c) S, is a tautology but S, is not a tautology.
(d) S, is not a tautology but S, is a tautology.
Long chain of friends: You are given a list of people, and statements of the form “x knows y”. You are asked to find, is there a chain of k distinct people, such as x1 knows x2, x2 knows x3, and xk-1 knows xk. Prove that this problem is NP-complete by using one of the known NP-complete problems (CLIQUE, 3-SAT, Hamiltonian Path, Hamiltonian Cycle, Independent Set, etc.)
