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 
  dbl : [o] --> o 
  dbls : [o] --> o 
  from : [o] --> o 
  indx : [o * o] --> o 
  mark : [o] --> o 
  nil : [] --> o 
  s : [o] --> o 
  sel : [o * o] --> o
