Q of the given QTRS could be disproven: (0) QTRS (1) DependencyPairsProof [EQUIVALENT, 6 ms] (2) QDP (3) DependencyGraphProof [EQUIVALENT, 0 ms] (4) AND (5) QDP (6) UsableRulesProof [EQUIVALENT, 0 ms] (7) QDP (8) QDPSizeChangeProof [EQUIVALENT, 0 ms] (9) YES (10) QDP (11) QDPOrderProof [EQUIVALENT, 6 ms] (12) QDP (13) NonTerminationLoopProof [COMPLETE, 2451 ms] (14) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: active(f(a, b, X)) -> mark(f(X, X, X)) active(c) -> mark(a) active(c) -> mark(b) mark(f(X1, X2, X3)) -> active(f(X1, X2, mark(X3))) mark(a) -> active(a) mark(b) -> active(b) mark(c) -> active(c) f(mark(X1), X2, X3) -> f(X1, X2, X3) f(X1, mark(X2), X3) -> f(X1, X2, X3) f(X1, X2, mark(X3)) -> f(X1, X2, X3) f(active(X1), X2, X3) -> f(X1, X2, X3) f(X1, active(X2), X3) -> f(X1, X2, X3) f(X1, X2, active(X3)) -> f(X1, X2, X3) Q is empty. ---------------------------------------- (1) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem. ---------------------------------------- (2) Obligation: Q DP problem: The TRS P consists of the following rules: ACTIVE(f(a, b, X)) -> MARK(f(X, X, X)) ACTIVE(f(a, b, X)) -> F(X, X, X) ACTIVE(c) -> MARK(a) ACTIVE(c) -> MARK(b) MARK(f(X1, X2, X3)) -> ACTIVE(f(X1, X2, mark(X3))) MARK(f(X1, X2, X3)) -> F(X1, X2, mark(X3)) MARK(f(X1, X2, X3)) -> MARK(X3) MARK(a) -> ACTIVE(a) MARK(b) -> ACTIVE(b) MARK(c) -> ACTIVE(c) F(mark(X1), X2, X3) -> F(X1, X2, X3) F(X1, mark(X2), X3) -> F(X1, X2, X3) F(X1, X2, mark(X3)) -> F(X1, X2, X3) F(active(X1), X2, X3) -> F(X1, X2, X3) F(X1, active(X2), X3) -> F(X1, X2, X3) F(X1, X2, active(X3)) -> F(X1, X2, X3) The TRS R consists of the following rules: active(f(a, b, X)) -> mark(f(X, X, X)) active(c) -> mark(a) active(c) -> mark(b) mark(f(X1, X2, X3)) -> active(f(X1, X2, mark(X3))) mark(a) -> active(a) mark(b) -> active(b) mark(c) -> active(c) f(mark(X1), X2, X3) -> f(X1, X2, X3) f(X1, mark(X2), X3) -> f(X1, X2, X3) f(X1, X2, mark(X3)) -> f(X1, X2, X3) f(active(X1), X2, X3) -> f(X1, X2, X3) f(X1, active(X2), X3) -> f(X1, X2, X3) f(X1, X2, active(X3)) -> f(X1, X2, X3) Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (3) DependencyGraphProof (EQUIVALENT) The approximation of the Dependency Graph [LPAR04,FROCOS05,EDGSTAR] contains 2 SCCs with 7 less nodes. ---------------------------------------- (4)
