0.00/0.00 NO 0.00/0.00 We consider the system theBenchmark. 0.00/0.00 0.00/0.00 Alphabet: 0.00/0.00 0.00/0.00 f : [nat * nat] --> nat 0.00/0.00 g : [nat -> nat] --> nat 0.00/0.00 0.00/0.00 Rules: 0.00/0.00 0.00/0.00 f(g(/\x.f(x, x)), g(/\y.f(y, y))) => (/\z.f(z, z)) g(/\u.f(u, u)) 0.00/0.00 0.00/0.00 This AFS is converted to an AFSM simply by replacing all free variables by meta-variables (with arity 0). 0.00/0.00 0.00/0.00 It is easy to see that this system is non-terminating: 0.00/0.00 0.00/0.00 f(g(/\x.f(x, x)), g(/\y.f(y, y))) 0.00/0.00 => (/\x.f(x, x)) g(/\y.f(y, y)) 0.00/0.00 => f(g(/\x.f(x, x)), g(/\y.f(y, y))) 0.00/0.00 0.00/0.00 That is, a term s reduces to a term t which instantiates s. 0.00/0.00 0.00/0.00 EOF
