Obligation:
Innermost
basic terms: {*,+}/{0,i}
Applied Processor:
DependencyPairs {dpKind_ = DT}
Proof:
We add the following dependency tuples:
Strict DPs
*#(x,+(y,z)) -> c_1(+#(*(x,y),*(x,z)),*#(x,y),*#(x,z))
*#(+(x,y),z) -> c_2(+#(*(x,z),*(y,z)),*#(x,z),*#(y,z))
+#(x,0()) -> c_3()
+#(x,i(x)) -> c_4()
+#(+(x,y),z) -> c_5(+#(x,+(y,z)),+#(y,z))
Weak DPs
and mark the set of starting terms.

Proof:
We replace rewrite rules by usable rules:
+#(x,0()) -> c_3()
+#(x,i(x)) -> c_4()

Applied Processor:
Trivial
Proof:
Consider the dependency graph
1:S:+#(x,0()) -> c_3()
2:S:+#(x,i(x)) -> c_4()
The dependency graph contains no loops, we remove all dependency pairs.
