% 8.34/1.46  
% 8.34/1.46  % SZS output start Proof
% 8.34/1.46  Take the following subset of the input axioms:
% 8.34/1.46    fof(a1_1, axiom, ![C, N, L, A2]: (accept_team(A2, L, C, N) <=> (accept_city(A2, C) & (accept_leader(A2, L) & accept_number(A2, N))))).
% 8.34/1.46    fof(a1_5, axiom, ![C2, L2, A2_2]: (any_agent_in_all_proposed_teams(A2_2, L2, C2) => accept_leader(A2_2, L2))).
% 8.34/1.46    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)))).
% 8.34/1.46    fof(event_37, axiom, the_agent_not_in_any_proposed_teams(countryamedicalorganization, christiancountrychumanitarianorganization, coastvillage)).
% 8.34/1.46    fof(event_38, axiom, any_agent_in_all_proposed_teams(countryamedicalorganization, christiancountrychumanitarianorganization, coastvillage)).
% 8.34/1.46    fof(less_property, axiom, ![X, Y]: (less(X, Y) <=> (~less(Y, X) & Y!=X))).
% 8.34/1.46    fof(query_4, conjecture, ~accept_team(countryamedicalorganization, countryahumanitarianorganization, coastvillage, n5)).
% 8.34/1.46  
% 8.34/1.46  Now clausify the problem and encode Horn clauses using encoding 3 of
% 8.34/1.46  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 8.34/1.46  We repeatedly replace C & s=t => u=v by the two clauses:
% 8.34/1.46    fresh(y, y, x1...xn) = u
% 8.34/1.46    C => fresh(s, t, x1...xn) = v
% 8.34/1.46  where fresh is a fresh function symbol and x1..xn are the free
% 8.34/1.46  variables of u and v.
% 8.34/1.46  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 8.34/1.46  input problem has no model of domain size 1).
% 8.34/1.46  
% 8.34/1.46  The encoding turns the above axioms into the following unit equations and goals:
% 8.34/1.46  
% 8.34/1.46  Axiom 1 (event_38): any_agent_in_all_proposed_teams(countryamedicalorganization, christiancountrychumanitarianorganization, coastvillage) = true2.
% 8.34/1.46  Axiom 2 (event_37): the_agent_not_in_any_proposed_teams(countryamedicalorganization, christiancountrychumanitarianorganization, coastvillage) = true2.
% 8.34/1.46  Axiom 3 (query_4): accept_team(countryamedicalorganization, countryahumanitarianorganization, coastvillage, n5) = true2.
% 8.34/1.46  Axiom 4 (a1_1): fresh91(X, X, Y, Z) = true2.
% 8.34/1.46  Axiom 5 (a1_5): fresh82(X, X, Y, Z) = true2.
% 8.34/1.46  Axiom 6 (a1_5): fresh82(any_agent_in_all_proposed_teams(X, Y, Z), true2, X, Y) = accept_leader(X, Y).
% 8.34/1.46  Axiom 7 (a1_1): fresh91(accept_team(X, Y, Z, W), true2, X, Z) = accept_city(X, Z).
% 8.34/1.46  
% 8.34/1.46  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).
% 8.34/1.46  The goal is true when:
% 8.34/1.46    X = countryamedicalorganization
% 8.34/1.46    Y = coastvillage
% 8.34/1.46    Z = christiancountrychumanitarianorganization
% 8.34/1.46  
% 8.34/1.46  Proof:
% 8.34/1.46    tuple(accept_city(countryamedicalorganization, coastvillage), accept_leader(countryamedicalorganization, christiancountrychumanitarianorganization), the_agent_not_in_any_proposed_teams(countryamedicalorganization, christiancountrychumanitarianorganization, coastvillage))
% 8.34/1.46  = { by axiom 2 (event_37) }
% 8.34/1.46    tuple(accept_city(countryamedicalorganization, coastvillage), accept_leader(countryamedicalorganization, christiancountrychumanitarianorganization), true2)
% 8.34/1.46  = { by axiom 7 (a1_1) R->L }
% 8.34/1.46    tuple(fresh91(accept_team(countryamedicalorganization, countryahumanitarianorganization, coastvillage, n5), true2, countryamedicalorganization, coastvillage), accept_leader(countryamedicalorganization, christiancountrychumanitarianorganization), true2)
% 8.34/1.46  = { by axiom 3 (query_4) }
% 8.34/1.46    tuple(fresh91(true2, true2, countryamedicalorganization, coastvillage), accept_leader(countryamedicalorganization, christiancountrychumanitarianorganization), true2)
% 8.34/1.46  = { by axiom 4 (a1_1) }
% 8.34/1.46    tuple(true2, accept_leader(countryamedicalorganization, christiancountrychumanitarianorganization), true2)
% 8.34/1.46  = { by axiom 6 (a1_5) R->L }
% 8.34/1.46    tuple(true2, fresh82(any_agent_in_all_proposed_teams(countryamedicalorganization, christiancountrychumanitarianorganization, coastvillage), true2, countryamedicalorganization, christiancountrychumanitarianorganization), true2)
% 8.34/1.46  = { by axiom 1 (event_38) }
% 8.34/1.46    tuple(true2, fresh82(true2, true2, countryamedicalorganization, christiancountrychumanitarianorganization), true2)
% 8.34/1.46  = { by axiom 5 (a1_5) }
% 8.34/1.46    tuple(true2, true2, true2)
% 8.34/1.46  % SZS output end Proof
% 8.34/1.46  
% 8.34/1.46  RESULT: Theorem (the conjecture is true).
