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 false : [] --> a 0.00/0.00 if : [a * b * b] --> b 0.00/0.00 true : [] --> a 0.00/0.00 until : [b -> a * b -> b * b] --> b 0.00/0.00 0.00/0.00 Rules: 0.00/0.00 0.00/0.00 if(true, x, y) => x 0.00/0.00 if(false, x, y) => y 0.00/0.00 until(f, g, x) => if(f x, x, until(f, g, g x)) 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 until(f, g, x) 0.00/0.00 => if(f x, x, until(f, g, g x)) 0.00/0.00 |> until(f, g, g x) 0.00/0.00 0.00/0.00 That is, a term s reduces to a term t which has a subterm that is an instance of the original term. 0.00/0.00 0.00/0.00 EOF
