By [NOC] we can switch to innermost. ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: app(app(lt, app(s, x)), app(s, y)) -> app(app(lt, x), y) app(app(lt, 0), app(s, y)) -> true app(app(lt, y), 0) -> false app(app(eq, x), x) -> true app(app(eq, app(s, x)), 0) -> false app(app(eq, 0), app(s, x)) -> false app(app(member, w), null) -> false app(app(member, w), app(app(app(fork, x), y), z)) -> app(app(app(if, app(app(lt, w), y)), app(app(member, w), x)), app(app(app(if, app(app(eq, w), y)), true), app(app(member, w), z))) The set Q consists of the following terms: app(app(lt, app(s, x0)), app(s, x1)) app(app(lt, 0), app(s, x0)) app(app(lt, x0), 0) app(app(eq, x0), x0) app(app(eq, app(s, x0)), 0) app(app(eq, 0), app(s, x0)) app(app(member, x0), null) app(app(member, x0), app(app(app(fork, x1), x2), x3)) ---------------------------------------- (3) DependencyPairsProof (EQUIVALENT) Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem. ---------------------------------------- (4) Obligation: Q DP problem: The TRS P consists of the following rules: APP(app(lt, app(s, x)), app(s, y)) -> APP(app(lt, x), y) APP(app(lt, app(s, x)), app(s, y)) -> APP(lt, x) APP(app(member, w), app(app(app(fork, x), y), z)) -> APP(app(app(if, app(app(lt, w), y)), app(app(member, w), x)), app(app(app(if, app(app(eq, w), y)), true), app(app(member, w), z))) APP(app(member, w), app(app(app(fork, x), y), z)) -> APP(app(if, app(app(lt, w), y)), app(app(member, w), x)) APP(app(member, w), app(app(app(fork, x), y), z)) -> APP(if, app(app(lt, w), y))
