The TRS R consists of the following rules: cond1(true, x, y) -> cond2(gr(x, y), x, y) cond2(true, x, y) -> cond1(gr(add(x, y), 0), p(x), y) cond2(false, x, y) -> cond3(eq(x, y), x, y) cond3(true, x, y) -> cond1(gr(add(x, y), 0), p(x), y) cond3(false, x, y) -> cond1(gr(add(x, y), 0), x, p(y)) gr(0, x) -> false gr(s(x), 0) -> true gr(s(x), s(y)) -> gr(x, y) add(0, x) -> x add(s(x), y) -> s(add(x, y)) eq(0, 0) -> true eq(0, s(x)) -> false eq(s(x), 0) -> false eq(s(x), s(y)) -> eq(x, y) p(0) -> 0 p(s(x)) -> x S is empty.

The TRS R consists of the following rules: cond1(true, x, y) -> cond2(gr(x, y), x, y) cond2(true, x, y) -> cond1(gr(add(x, y), 0), p(x), y) cond2(false, x, y) -> cond3(eq(x, y), x, y) cond3(true, x, y) -> cond1(gr(add(x, y), 0), p(x), y) cond3(false, x, y) -> cond1(gr(add(x, y), 0), x, p(y)) gr(0, x) -> false gr(s(x), 0) -> true gr(s(x), s(y)) -> gr(x, y) add(0, x) -> x add(s(x), y) -> s(add(x, y)) eq(0, 0) -> true eq(0, s(x)) -> false eq(s(x), 0) -> false eq(s(x), s(y)) -> eq(x, y) p(0) -> 0 p(s(x)) -> x S is empty. Rewrite Strategy: FULL ---------------------------------------- (3) DecreasingLoopProof (LOWER BOUND(ID)) The following loop(s) give(s) rise to the lower bound Omega(n^1): The rewrite sequence add(s(x), y) ->^+ s(add(x, y)) gives rise to a decreasing loop by considering the right hand sides subterm at position [0]. The pumping substitution is [x / s(x)]. The result substitution is [ ]. popout
