% 7.72/1.35 % SZS status Theorem
% 7.72/1.35
% 7.72/1.35 % SZS output start Proof
% 7.72/1.35 Take the following subset of the input axioms:
% 7.72/1.35 fof(a1_5, axiom, ![C, L, A2]: (any_agent_in_all_proposed_teams(A2, L, C) => accept_leader(A2, L))).
% 7.72/1.35 fof(a1_6, axiom, ![A, C2, L2]: (the_agent_not_in_any_proposed_teams(A, L2, C2) => ~(accept_city(A, C2) & accept_leader(A, L2)))).
% 7.72/1.35 fof(event_11, axiom, the_agent_not_in_any_proposed_teams(muslimcountrybhumanitarianorganization, countryacivilorganization, towna)).
% 7.72/1.35 fof(event_12, axiom, any_agent_in_all_proposed_teams(muslimcountrybhumanitarianorganization, countryacivilorganization, towna)).
% 7.72/1.35 fof(less_property, axiom, ![X, Y]: (less(X, Y) <=> (~less(Y, X) & Y!=X))).
% 7.72/1.35 fof(query_15, conjecture, ?[X2, Y2]: ~accept_city(X2, Y2)).
% 7.72/1.35
% 7.72/1.35 Now clausify the problem and encode Horn clauses using encoding 3 of
% 7.72/1.35 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 7.72/1.35 We repeatedly replace C & s=t => u=v by the two clauses:
% 7.72/1.35 fresh(y, y, x1...xn) = u
% 7.72/1.35 C => fresh(s, t, x1...xn) = v
% 7.72/1.35 where fresh is a fresh function symbol and x1..xn are the free
% 7.72/1.35 variables of u and v.
% 7.72/1.35 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 7.72/1.35 input problem has no model of domain size 1).
% 7.72/1.35
% 7.72/1.35 The encoding turns the above axioms into the following unit equations and goals:
% 7.72/1.35
% 7.72/1.35 Axiom 1 (query_15): accept_city(X, Y) = true2.
% 7.72/1.35 Axiom 2 (event_12): any_agent_in_all_proposed_teams(muslimcountrybhumanitarianorganization, countryacivilorganization, towna) = true2.
% 7.72/1.35 Axiom 3 (event_11): the_agent_not_in_any_proposed_teams(muslimcountrybhumanitarianorganization, countryacivilorganization, towna) = true2.
% 7.72/1.35 Axiom 4 (a1_5): fresh82(X, X, Y, Z) = true2.
% 7.72/1.35 Axiom 5 (a1_5): fresh82(any_agent_in_all_proposed_teams(X, Y, Z), true2, X, Y) = accept_leader(X, Y).
% 7.72/1.35
% 7.72/1.35 Goal 1 (a1_6): tuple(accept_city(X, Y), accept_leader(X, Z), the_agent_not_in_any_proposed_teams(X, Z, Y)) = tuple(true2, true2, true2).
% 7.72/1.35 The goal is true when:
% 7.72/1.35 X = muslimcountrybhumanitarianorganization
% 7.72/1.35 Y = towna
% 7.72/1.35 Z = countryacivilorganization
% 7.72/1.35
% 7.72/1.35 Proof:
% 7.72/1.35 tuple(accept_city(muslimcountrybhumanitarianorganization, towna), accept_leader(muslimcountrybhumanitarianorganization, countryacivilorganization), the_agent_not_in_any_proposed_teams(muslimcountrybhumanitarianorganization, countryacivilorganization, towna))
% 7.72/1.35 = { by axiom 1 (query_15) }
% 7.72/1.35 tuple(true2, accept_leader(muslimcountrybhumanitarianorganization, countryacivilorganization), the_agent_not_in_any_proposed_teams(muslimcountrybhumanitarianorganization, countryacivilorganization, towna))
% 7.72/1.35 = { by axiom 3 (event_11) }
% 7.72/1.35 tuple(true2, accept_leader(muslimcountrybhumanitarianorganization, countryacivilorganization), true2)
% 7.72/1.35 = { by axiom 5 (a1_5) R->L }
% 7.72/1.35 tuple(true2, fresh82(any_agent_in_all_proposed_teams(muslimcountrybhumanitarianorganization, countryacivilorganization, towna), true2, muslimcountrybhumanitarianorganization, countryacivilorganization), true2)
% 7.72/1.35 = { by axiom 2 (event_12) }
% 7.72/1.35 tuple(true2, fresh82(true2, true2, muslimcountrybhumanitarianorganization, countryacivilorganization), true2)
% 7.72/1.35 = { by axiom 4 (a1_5) }
% 7.72/1.35 tuple(true2, true2, true2)
% 7.72/1.35 % SZS output end Proof
% 7.72/1.35
% 7.72/1.35 RESULT: Theorem (the conjecture is true).
