*** 1 Progress [(O(1),O(1))] *** Considered Problem: Strict DP Rules: Strict TRS Rules: 0() -> 1() f(s(x)) -> f(g(x,x)) g(0(),1()) -> s(0()) Weak DP Rules: Weak TRS Rules: Signature: {0/0,f/1,g/2} / {1/0,s/1} Obligation: Innermost basic terms: {0,f,g}/{1,s} Applied Processor: InnermostRuleRemoval Proof: Arguments of following rules are not normal-forms. g(0(),1()) -> s(0()) All above mentioned rules can be savely removed. *** 1.1 Progress [(O(1),O(1))] *** Considered Problem: Strict DP Rules: Strict TRS Rules: 0() -> 1() f(s(x)) -> f(g(x,x)) Weak DP Rules: Weak TRS Rules: Signature: {0/0,f/1,g/2} / {1/0,s/1} Obligation: Innermost basic terms: {0,f,g}/{1,s} Applied Processor: DependencyPairs {dpKind_ = DT} Proof: We add the following dependency tuples: Strict DPs 0#() -> c_1() f#(s(x)) -> c_2(f#(g(x,x)),g#(x,x)) Weak DPs and mark the set of starting terms. *** 1.1.1 Progress [(O(1),O(1))] *** Considered Problem: Strict DP Rules: 0#() -> c_1() f#(s(x)) -> c_2(f#(g(x,x)),g#(x,x)) Strict TRS Rules: Weak DP Rules: Weak TRS Rules: 0() -> 1() f(s(x)) -> f(g(x,x)) Signature: {0/0,f/1,g/2,0#/0,f#/1,g#/2} / {1/0,s/1,c_1/0,c_2/2} Obligation: Innermost basic terms: {0#,f#,g#}/{1,s} Applied Processor: UsableRules Proof: We replace rewrite rules by usable rules: 0#() -> c_1() f#(s(x)) -> c_2(f#(g(x,x)),g#(x,x)) *** 1.1.1.1 Progress [(O(1),O(1))] *** Considered Problem: Strict DP Rules: 0#() -> c_1() f#(s(x)) -> c_2(f#(g(x,x)),g#(x,x)) Strict TRS Rules: Weak DP Rules: Weak TRS Rules: Signature: {0/0,f/1,g/2,0#/0,f#/1,g#/2} / {1/0,s/1,c_1/0,c_2/2} Obligation: Innermost basic terms: {0#,f#,g#}/{1,s} Applied Processor: Trivial Proof: Consider the dependency graph 1:S:0#() -> c_1() 2:S:f#(s(x)) -> c_2(f#(g(x,x)),g#(x,x)) The dependency graph contains no loops, we remove all dependency pairs. *** 1.1.1.1.1 Progress [(O(1),O(1))] *** Considered Problem: Strict DP Rules: Strict TRS Rules: Weak DP Rules: Weak TRS Rules: Signature: {0/0,f/1,g/2,0#/0,f#/1,g#/2} / {1/0,s/1,c_1/0,c_2/2} Obligation: Innermost basic terms: {0#,f#,g#}/{1,s} Applied Processor: EmptyProcessor Proof: The problem is already closed.
