% 24.77/3.50  % SZS output start Proof
% 24.77/3.50  Take the following subset of the input axioms:
% 24.77/3.50    fof(cls_CHAINED_0, axiom, c_SEQ_OLIMSEQ(c_COMBB(c_Complex_OIm, c_COMBB(v_s, c_COMBB(v_f____, v_ga____, tc_nat, tc_nat, tc_nat), tc_nat, tc_Complex_Ocomplex, tc_nat), tc_Complex_Ocomplex, tc_RealDef_Oreal, tc_nat), v_sko__CHAINED__1(v_f____, v_ga____, v_s), tc_RealDef_Oreal)).
% 24.77/3.50    fof(cls_conjecture_0, negated_conjecture, ~v_thesis____).
% 24.77/3.50    fof(cls_conjecture_1, negated_conjecture, ![V_x]: (v_thesis____ | ~c_SEQ_OLIMSEQ(c_COMBB(c_Complex_OIm, c_COMBB(v_s, c_COMBB(v_f____, v_ga____, tc_nat, tc_nat, tc_nat), tc_nat, tc_Complex_Ocomplex, tc_nat), tc_Complex_Ocomplex, tc_RealDef_Oreal, tc_nat), V_x, tc_RealDef_Oreal))).
% 24.77/3.50  
% 24.77/3.50  Now clausify the problem and encode Horn clauses using encoding 3 of
% 24.77/3.50  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 24.77/3.50  We repeatedly replace C & s=t => u=v by the two clauses:
% 24.77/3.50    fresh(y, y, x1...xn) = u
% 24.77/3.50    C => fresh(s, t, x1...xn) = v
% 24.77/3.50  where fresh is a fresh function symbol and x1..xn are the free
% 24.77/3.50  variables of u and v.
% 24.77/3.50  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 24.77/3.50  input problem has no model of domain size 1).
% 24.77/3.50  
% 24.77/3.50  The encoding turns the above axioms into the following unit equations and goals:
% 24.77/3.50  
% 24.77/3.50  Axiom 1 (cls_conjecture_1): fresh203(X, X) = true2.
% 24.77/3.50  Axiom 2 (cls_conjecture_1): fresh203(c_SEQ_OLIMSEQ(c_COMBB(c_Complex_OIm, c_COMBB(v_s, c_COMBB(v_f____, v_ga____, tc_nat, tc_nat, tc_nat), tc_nat, tc_Complex_Ocomplex, tc_nat), tc_Complex_Ocomplex, tc_RealDef_Oreal, tc_nat), X, tc_RealDef_Oreal), true2) = v_thesis____.
% 24.77/3.50  Axiom 3 (cls_CHAINED_0): c_SEQ_OLIMSEQ(c_COMBB(c_Complex_OIm, c_COMBB(v_s, c_COMBB(v_f____, v_ga____, tc_nat, tc_nat, tc_nat), tc_nat, tc_Complex_Ocomplex, tc_nat), tc_Complex_Ocomplex, tc_RealDef_Oreal, tc_nat), v_sko__CHAINED__1(v_f____, v_ga____, v_s), tc_RealDef_Oreal) = true2.
% 24.77/3.50  
% 24.77/3.50  Goal 1 (cls_conjecture_0): v_thesis____ = true2.
% 24.77/3.50  Proof:
% 24.77/3.50    v_thesis____
% 24.77/3.50  = { by axiom 2 (cls_conjecture_1) R->L }
% 24.77/3.50    fresh203(c_SEQ_OLIMSEQ(c_COMBB(c_Complex_OIm, c_COMBB(v_s, c_COMBB(v_f____, v_ga____, tc_nat, tc_nat, tc_nat), tc_nat, tc_Complex_Ocomplex, tc_nat), tc_Complex_Ocomplex, tc_RealDef_Oreal, tc_nat), v_sko__CHAINED__1(v_f____, v_ga____, v_s), tc_RealDef_Oreal), true2)
% 24.77/3.50  = { by axiom 3 (cls_CHAINED_0) }
% 24.77/3.50    fresh203(true2, true2)
% 24.77/3.50  = { by axiom 1 (cls_conjecture_1) }
% 24.77/3.50    true2
% 24.77/3.50  % SZS output end Proof
% 24.77/3.50  
% 24.77/3.50  RESULT: Unsatisfiable (the axioms are contradictory).
