The TRS R consists of the following rules: f(X, n__g(X), Y) -> f(activate(Y), activate(Y), activate(Y)) g(b) -> c b -> c g(X) -> n__g(X) activate(n__g(X)) -> g(X) activate(X) -> X S is empty. Rewrite Strategy: FULL ---------------------------------------- (1) NestedDefinedSymbolProof (UPPER BOUND(ID)) The following defined symbols can occur below the 0th argument of f: activate, g The following defined symbols can occur below the 1th argument of f: activate, g The following defined symbols can occur below the 2th argument of f: activate, g The following defined symbols can occur below the 0th argument of activate: activate, g Hence, the left-hand sides of the following rules are not basic-reachable and can be removed: g(b) -> c ---------------------------------------- (2) Obligation: The Runtime Complexity (full) of the given CpxTRS could be proven to be BOUNDS(1, 1). The TRS R consists of the following rules: f(X, n__g(X), Y) -> f(activate(Y), activate(Y), activate(Y)) b -> c g(X) -> n__g(X) activate(n__g(X)) -> g(X) activate(X) -> X S is empty. Rewrite Strategy: FULL ---------------------------------------- (3) NarrowingOnBasicTermsTerminatesProof (FINISHED) Constant runtime complexity proven by termination of constructor-based narrowing. The maximal most general narrowing sequences give rise to the following rewrite sequences: activate(n__g(x0)) ->^* n__g(x0) g(x0) ->^* n__g(x0) b ->^* c f(x0, n__g(x0), x1) ->^* f(x1, x1, x1) f(x0, n__g(x0), n__g(x1)) ->^* f(n__g(x1), n__g(x1), n__g(x1)) ---------------------------------------- (4) BOUNDS(1, 1)
