MAYBE
We consider the system theBenchmark.

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

  0 : [] --> o 
  a : [] --> o 
  b : [] --> o 
  c : [] --> o 
  false : [] --> o 
  gcd : [o * o] --> o 
  gcd2 : [o * o * o] --> o 
  if1 : [o * o * o * o * o * o * o] --> o 
  if2 : [o * o * o * o * o * o] --> o 
  if3 : [o * o * o * o * o] --> o 
  if4 : [o * o * o * o] --> o 
  inc : [o] --> o 
  le : [o * o] --> o 
  minus : [o * o] --> o 
  neededIterations : [o] --> o 
  pair : [o * o] --> o 
  result : [o] --> o 
  s : [o] --> o 
  true : [] --> o 

  gcd(X, Y) => gcd2(X, Y, 0)

  if2(false, X, Y, Z, U, V) => if3(X, Y, Z, U, V)

  le(s(X), 0) => false 
  le(0, X) => true 
  le(s(X), s(Y)) => le(X, Y)
