% 9.16/1.70 fresh(y, y, x1...xn) = u
% 9.16/1.70 C => fresh(s, t, x1...xn) = v
% 9.16/1.70 where fresh is a fresh function symbol and x1..xn are the free
% 9.16/1.70 variables of u and v.
% 9.16/1.70 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 9.16/1.70 input problem has no model of domain size 1).
% 9.16/1.70
% 9.16/1.70 The encoding turns the above axioms into the following unit equations and goals:
% 9.16/1.70
% 9.16/1.70 Axiom 1 (main_2): p15(y17) = true.
% 9.16/1.70 Axiom 2 (main_3): p15(y16) = true.
% 9.16/1.70
% 9.16/1.70 Goal 1 (main_166): p15(y16) = true.
% 9.16/1.70 Proof:
% 9.16/1.70 p15(y16)
% 9.16/1.70 = { by axiom 2 (main_3) }
% 9.16/1.70 true
% 9.16/1.70
% 9.16/1.70 Goal 2 (main_165): p15(y17) = true.
% 9.16/1.70 Proof:
% 9.16/1.70 p15(y17)
% 9.16/1.70 = { by axiom 1 (main_2) }
% 9.16/1.70 true
% 9.16/1.70 % SZS output end Proof
% 9.16/1.70
% 9.16/1.70 RESULT: Theorem (the conjecture is true).
