TIMEOUT

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

Strict Trs:
  { eq(0(), 0()) -> true()
  , eq(0(), s(x)) -> false()
  , eq(s(x), 0()) -> false()
  , eq(s(x), s(y)) -> eq(x, y)
  , or(true(), y) -> true()
  , or(false(), y) -> y
  , union(empty(), h) -> h
  , union(edge(x, y, i), h) -> edge(x, y, union(i, h))
  , reach(x, y, empty(), h) -> false()
  , reach(x, y, edge(u, v, i), h) ->
    if_reach_1(eq(x, u), x, y, edge(u, v, i), h)
  , if_reach_1(true(), x, y, edge(u, v, i), h) ->
    if_reach_2(eq(y, v), x, y, edge(u, v, i), h)
  , if_reach_1(false(), x, y, edge(u, v, i), h) ->
    reach(x, y, i, edge(u, v, h))
  , if_reach_2(true(), x, y, edge(u, v, i), h) -> true()
  , if_reach_2(false(), x, y, edge(u, v, i), h) ->
    or(reach(x, y, i, h), reach(v, y, union(i, h), empty())) }

  innermost runtime complexity
Answer:
  TIMEOUT

Computation stopped due to timeout after 10.0 seconds.

Arrrr..
