MAYBE

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict Trs:
  { active(minus(0(), Y)) -> mark(0())
  , active(minus(s(X), s(Y))) -> mark(minus(X, Y))
  , active(s(X)) -> s(active(X))
  , active(geq(X, 0())) -> mark(true())
  , active(geq(0(), s(Y))) -> mark(false())
  , active(geq(s(X), s(Y))) -> mark(geq(X, Y))
  , active(div(X1, X2)) -> div(active(X1), X2)
  , active(div(0(), s(Y))) -> mark(0())
  , active(div(s(X), s(Y))) ->
    mark(if(geq(X, Y), s(div(minus(X, Y), s(Y))), 0()))
  , active(if(X1, X2, X3)) -> if(active(X1), X2, X3)
  , active(if(true(), X, Y)) -> mark(X)
  , active(if(false(), X, Y)) -> mark(Y)
  , minus(ok(X1), ok(X2)) -> ok(minus(X1, X2))
  , s(mark(X)) -> mark(s(X))
  , s(ok(X)) -> ok(s(X))
  , geq(ok(X1), ok(X2)) -> ok(geq(X1, X2))
  , div(mark(X1), X2) -> mark(div(X1, X2))
  , div(ok(X1), ok(X2)) -> ok(div(X1, X2))
  , if(mark(X1), X2, X3) -> mark(if(X1, X2, X3))
  , if(ok(X1), ok(X2), ok(X3)) -> ok(if(X1, X2, X3))
  , proper(minus(X1, X2)) -> minus(proper(X1), proper(X2))
  , proper(0()) -> ok(0())
  , proper(s(X)) -> s(proper(X))
  , proper(geq(X1, X2)) -> geq(proper(X1), proper(X2))
  , proper(true()) -> ok(true())
  , proper(false()) -> ok(false())
  , proper(div(X1, X2)) -> div(proper(X1), proper(X2))
  , proper(if(X1, X2, X3)) -> if(proper(X1), proper(X2), proper(X3))
