We consider the following Problem: Strict Trs: { f(c(a(), z, x)) -> b(a(), z) , b(x, b(z, y)) -> f(b(f(f(z)), c(x, z, y))) , b(y, z) -> z} StartTerms: basic terms Strategy: innermost Certificate: YES(?,O(n^1)) Proof: Arguments of following rules are not normal-forms: {b(x, b(z, y)) -> f(b(f(f(z)), c(x, z, y)))} All above mentioned rules can be savely removed. We consider the following Problem: Strict Trs: { f(c(a(), z, x)) -> b(a(), z) , b(y, z) -> z} StartTerms: basic terms Strategy: innermost Certificate: YES(?,O(n^1)) Proof: The weightgap principle applies, where following rules are oriented strictly: TRS Component: {b(y, z) -> z} Interpretation of nonconstant growth: ------------------------------------- The following argument positions are usable: Uargs(f) = {}, Uargs(c) = {}, Uargs(b) = {} We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation: Interpretation Functions: f(x1) = [1 0] x1 + [1] [1 0] [1] c(x1, x2, x3) = [1 0] x1 + [1 0] x2 + [0 0] x3 + [0] [0 1] [0 0] [0 0] [0] a() = [0] [0] b(x1, x2) = [0 0] x1 + [1 0] x2 + [1] [0 0] [0 1] [1] The strictly oriented rules are moved into the weak component. We consider the following Problem: Strict Trs: {f(c(a(), z, x)) -> b(a(), z)} Weak Trs: {b(y, z) -> z} StartTerms: basic terms Strategy: innermost Certificate: YES(?,O(n^1)) Proof: The weightgap principle applies, where following rules are oriented strictly: TRS Component: {f(c(a(), z, x)) -> b(a(), z)} Interpretation of nonconstant growth: ------------------------------------- The following argument positions are usable: Uargs(f) = {}, Uargs(c) = {}, Uargs(b) = {} We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation: Interpretation Functions: f(x1) = [1 0] x1 + [1] [0 1] [1] c(x1, x2, x3) = [0 0] x1 + [1 0] x2 + [0 0] x3 + [0] [0 0] [0 1] [0 0] [0] a() = [0] [0] b(x1, x2) = [0 0] x1 + [1 0] x2 + [0] [0 0] [0 1] [1] The strictly oriented rules are moved into the weak component. We consider the following Problem: Weak Trs: { f(c(a(), z, x)) -> b(a(), z) , b(y, z) -> z} StartTerms: basic terms Strategy: innermost Certificate: YES(O(1),O(1)) Proof: We consider the following Problem: Weak Trs: { f(c(a(), z, x)) -> b(a(), z) , b(y, z) -> z} StartTerms: basic terms Strategy: innermost Certificate: YES(O(1),O(1)) Proof: Empty rules are trivially bounded Hurray, we answered YES(?,O(n^1))
