MAYBE 'Pop* with parameter subtitution (timeout of 60.0 seconds)' ----------------------------------------------------------- Answer: MAYBE Input Problem: innermost runtime-complexity with respect to Rules: { 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 , and(true(), y) -> y , and(false(), y) -> false() , size(empty()) -> 0() , size(edge(x, y, i)) -> s(size(i)) , le(0(), y) -> true() , le(s(x), 0()) -> false() , le(s(x), s(y)) -> le(x, y) , reachable(x, y, i) -> reach(x, y, 0(), i, i) , reach(x, y, c, i, j) -> if1(eq(x, y), x, y, c, i, j) , if1(true(), x, y, c, i, j) -> true() , if1(false(), x, y, c, i, j) -> if2(le(c, size(j)), x, y, c, i, j) , if2(false(), x, y, c, i, j) -> false() , if2(true(), x, y, c, empty(), j) -> false() , if2(true(), x, y, c, edge(u, v, i), j) -> or(if2(true(), x, y, c, i, j), and(eq(x, u), reach(v, y, s(c), j, j)))} Proof Output: The input cannot be shown compatible
