0.00/0.05 YES 0.00/0.05 We consider the system theBenchmark. 0.00/0.05 0.00/0.05 Alphabet: 0.00/0.05 0.00/0.05 f : [o -> o] --> o 0.00/0.05 g : [] --> o -> o 0.00/0.05 0.00/0.05 Rules: 0.00/0.05 0.00/0.05 f(g) => f(/\x.g x) 0.00/0.05 0.00/0.05 This AFS is converted to an AFSM simply by replacing all free variables by meta-variables (with arity 0). 0.00/0.05 0.00/0.05 We use the dependency pair framework as described in [Kop12, Ch. 6/7], with dynamic dependency pairs. 0.00/0.05 0.00/0.05 We thus obtain the following dependency pair problem (P_0, R_0, minimal, formative): 0.00/0.05 0.00/0.05 Dependency Pairs P_0: 0.00/0.05 0.00/0.05 0] f#(g) =#> f#(/\x.g x) 0.00/0.05 0.00/0.05 Rules R_0: 0.00/0.05 0.00/0.05 f(g) => f(/\x.g x) 0.00/0.05 0.00/0.05 Thus, the original system is terminating if (P_0, R_0, minimal, formative) is finite. 0.00/0.05 0.00/0.05 We consider the dependency pair problem (P_0, R_0, minimal, formative). 0.00/0.05 0.00/0.05 We place the elements of P in a dependency graph approximation G (see e.g. [Kop12, Thm. 7.27, 7.29], as follows: 0.00/0.05 0.00/0.05 * 0 : 0.00/0.05 0.00/0.05 This graph has no strongly connected components. By [Kop12, Thm. 7.31], this implies finiteness of the dependency pair problem. 0.00/0.05 0.00/0.05 As all dependency pair problems were succesfully simplified with sound (and complete) processors until nothing remained, we conclude termination. 0.00/0.05 0.00/0.05 0.00/0.05 +++ Citations +++ 0.00/0.05 0.00/0.05 [Kop12] C.
