MAYBE
We consider the system theBenchmark.

We are asked to determine termination of the following first-order TRS.

  0 : [] --> o 
  active : [o] --> o 
  cons : [o * o] --> o 
  from : [o] --> o 
  length : [o] --> o 
  length1 : [o] --> o 
  mark : [o] --> o 
  nil : [] --> o 
  ok : [o] --> o 
  proper : [o] --> o 
  s : [o] --> o 
  top : [o] --> o 

  active(from(X)) => mark(cons(X, from(s(X)))) 
  active(length(nil)) => mark(0) 
  active(length(cons(X, Y))) => mark(s(length1(Y))) 
  active(length1(X)) => mark(length(X)) 
  active(from(X)) => from(active(X)) 
  active(cons(X, Y)) => cons(active(X), Y) 
  active(s(X)) => s(active(X)) 
  from(mark(X)) => mark(from(X)) 
  cons(mark(X), Y) => mark(cons(X, Y)) 
  s(mark(X)) => mark(s(X)) 
  proper(from(X)) => from(proper(X)) 
  proper(cons(X, Y)) => cons(proper(X), proper(Y)) 
  proper(s(X)) => s(proper(X)) 
  proper(length(X)) => length(proper(X)) 
  proper(nil) => ok(nil) 
  proper(0) => ok(0) 
  proper(length1(X)) => length1(proper(X)) 
  from(ok(X)) => ok(from(X)) 
  cons(ok(X), ok(Y)) => ok(cons(X, Y)) 
  s(ok(X)) => ok(s(X)) 
  length(ok(X)) => ok(length(X)) 
  length1(ok(X)) => ok(length1(X)) 
  top(mark(X)) => top(proper(X)) 
  top(ok(X)) => top(active(X))
