Strict TRS Rules:
b(x,b(z,y)) -> f(b(f(f(z)),c(x,z,y)))
b(y,z) -> z

Weak TRS Rules:
Signature:
{b/2,f/1} / {a/0,c/3}
Obligation:
Innermost
basic terms: {b,f}/{a,c}
Applied Processor:
InnermostRuleRemoval
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.

Applied Processor:
DependencyPairs {dpKind_ = DT}
Proof:
We add the following dependency tuples:
Strict DPs
b#(y,z) -> c_1()
f#(c(a(),z,x)) -> c_2(b#(a(),z))
Weak DPs
and mark the set of starting terms.
*** 1.1.1 Progress [(O(1),O(1))] ***

Applied Processor:
UsableRules
Proof:
We replace rewrite rules by usable rules:
b#(y,z) -> c_1()
f#(c(a(),z,x)) -> c_2(b#(a(),z))

Applied Processor:
Trivial
Proof:
Consider the dependency graph
1:S:b#(y,z) -> c_1()
2:S:f#(c(a(),z,x)) -> c_2(b#(a(),z))
-->_1 b#(y,z) -> c_1():1
The dependency graph contains no loops, we remove all dependency pairs.
