TIMEOUT

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

Strict Trs:
  { car(cons(x, l)) -> x
  , cddr(cons(x, cons(y, l))) -> l
  , cddr(cons(x, nil())) -> nil()
  , cddr(nil()) -> nil()
  , cadr(cons(x, cons(y, l))) -> y
  , isZero(0()) -> true()
  , isZero(s(x)) -> false()
  , plus(x, y) -> ifplus(isZero(x), x, y)
  , ifplus(true(), x, y) -> y
  , ifplus(false(), x, y) -> s(plus(p(x), y))
  , p(0()) -> 0()
  , p(s(x)) -> x
  , times(x, y) -> iftimes(isZero(x), x, y)
  , iftimes(true(), x, y) -> 0()
  , iftimes(false(), x, y) -> plus(y, times(p(x), y))
  , shorter(cons(x, l), 0()) -> false()
  , shorter(cons(x, l), s(y)) -> shorter(l, y)
  , shorter(nil(), y) -> true()
  , prod(l) -> if(shorter(l, 0()), shorter(l, s(0())), l)
  , if(true(), b, l) -> s(0())
  , if(false(), b, l) -> if2(b, l)
  , if2(true(), l) -> car(l)
  , if2(false(), l) -> prod(cons(times(car(l), cadr(l)), cddr(l))) }

Answer:
  TIMEOUT

Computation stopped due to timeout after 60.0 seconds.

Arrrr..
