* Step 1: ToInnermost WORST_CASE(?,O(1)) + Considered Problem: - Strict TRS: a(b(x)) -> a(c(b(x))) - Signature: {a/1} / {b/1,c/1} - Obligation: runtime complexity wrt. defined symbols {a} and constructors {b,c} + Applied Processor: ToInnermost + Details: switch to innermost, as the system is overlay and right linear and does not contain weak rules * Step 2: DependencyPairs WORST_CASE(?,O(1)) + Considered Problem: - Strict TRS: a(b(x)) -> a(c(b(x))) - Signature: {a/1} / {b/1,c/1} - Obligation: innermost runtime complexity wrt. defined symbols {a} and constructors {b,c} + Applied Processor: DependencyPairs {dpKind_ = DT} + Details: We add the following dependency tuples: Strict DPs a#(b(x)) -> c_1(a#(c(b(x)))) Weak DPs and mark the set of starting terms. * Step 3: UsableRules WORST_CASE(?,O(1)) + Considered Problem: - Strict DPs: a#(b(x)) -> c_1(a#(c(b(x)))) - Weak TRS: a(b(x)) -> a(c(b(x))) - Signature: {a/1,a#/1} / {b/1,c/1,c_1/1} - Obligation: innermost runtime complexity wrt. defined symbols {a#} and constructors {b,c} + Applied Processor: UsableRules + Details: We replace rewrite rules by usable rules: a#(b(x)) -> c_1(a#(c(b(x)))) * Step 4: Trivial WORST_CASE(?,O(1)) + Considered Problem: - Strict DPs: a#(b(x)) -> c_1(a#(c(b(x)))) - Signature: {a/1,a#/1} / {b/1,c/1,c_1/1} - Obligation: innermost runtime complexity wrt. defined symbols {a#} and constructors {b,c} + Applied Processor: Trivial + Details: Consider the dependency graph 1:S:a#(b(x)) -> c_1(a#(c(b(x)))) The dependency graph contains no loops, we remove all dependency pairs. * Step 5: EmptyProcessor WORST_CASE(?,O(1)) + Considered Problem: - Signature: {a/1,a#/1} / {b/1,c/1,c_1/1} - Obligation: innermost runtime complexity wrt. defined symbols {a#} and constructors {b,c} + Applied Processor: EmptyProcessor + Details: The problem is already closed.
