The TRS R consists of the following rules: function(iszero, 0, dummy, dummy2) -> true function(iszero, s(x), dummy, dummy2) -> false function(p, 0, dummy, dummy2) -> 0 function(p, s(0), dummy, dummy2) -> 0 function(p, s(s(x)), dummy, dummy2) -> s(function(p, s(x), x, x)) function(plus, dummy, x, y) -> function(if, function(iszero, x, x, x), x, y) function(if, true, x, y) -> y function(if, false, x, y) -> function(plus, function(third, x, y, y), function(p, x, x, y), s(y)) function(third, x, y, z) -> z S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (1) DerivationalComplexityToRuntimeComplexityProof (BOTH BOUNDS(ID, ID)) The following rules have been added to S to convert the given derivational complexity problem to a runtime complexity problem: encArg(iszero) -> iszero encArg(0) -> 0 encArg(true) -> true encArg(s(x_1)) -> s(encArg(x_1)) encArg(false) -> false encArg(p) -> p encArg(plus) -> plus encArg(if) -> if encArg(third) -> third encArg(cons_function(x_1, x_2, x_3, x_4)) -> function(encArg(x_1), encArg(x_2), encArg(x_3), encArg(x_4)) encode_function(x_1, x_2, x_3, x_4) -> function(encArg(x_1), encArg(x_2), encArg(x_3), encArg(x_4)) encode_iszero -> iszero encode_0 -> 0 encode_true -> true encode_s(x_1) -> s(encArg(x_1)) encode_false -> false encode_p -> p encode_plus -> plus encode_if -> if encode_third -> third ---------------------------------------- (2) Obligation: The Runtime Complexity (innermost) of the given CpxRelTRS could be proven to be BOUNDS(n^1, INF). The TRS R consists of the following rules: function(iszero, 0, dummy, dummy2) -> true function(iszero, s(x), dummy, dummy2) -> false function(p, 0, dummy, dummy2) -> 0 function(p, s(0), dummy, dummy2) -> 0 function(p, s(s(x)), dummy, dummy2) -> s(function(p, s(x), x, x)) function(plus, dummy, x, y) -> function(if, function(iszero, x, x, x), x, y) function(if, true, x, y) -> y function(if, false, x, y) -> function(plus, function(third, x, y, y), function(p, x, x, y), s(y)) function(third, x, y, z) -> z The (relative) TRS S consists of the following rules: encArg(iszero) -> iszero encArg(0) -> 0 encArg(true) -> true encArg(s(x_1)) -> s(encArg(x_1)) encArg(false) -> false encArg(p) -> p encArg(plus) -> plus encArg(if) -> if encArg(third) -> third
