MAYBE
We consider the system theBenchmark.

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

  0 : [] --> o 
  a!6220!6220from : [o] --> o 
  a!6220!6220sel : [o * o] --> o 
  cons : [o * o] --> o 
  from : [o] --> o 
  mark : [o] --> o 
  s : [o] --> o 
  sel : [o * o] --> o 

  a!6220!6220from(X) => cons(mark(X), from(s(X))) 
  a!6220!6220sel(0, cons(X, Y)) => mark(X) 
  a!6220!6220sel(s(X), cons(Y, Z)) => a!6220!6220sel(mark(X), mark(Z)) 
  mark(from(X)) => a!6220!6220from(mark(X)) 
  mark(sel(X, Y)) => a!6220!6220sel(mark(X), mark(Y)) 
  mark(cons(X, Y)) => cons(mark(X), Y) 
  mark(s(X)) => s(mark(X)) 
  mark(0) => 0 
  a!6220!6220from(X) => from(X) 
  a!6220!6220sel(X, Y) => sel(X, Y)
