We return to the main proof. Consider the set of all dependency
pairs
:
{ 1: a__and^#(true(), X) -> c_1(mark^#(X))
, 2: mark^#(and(X1, X2)) -> c_4(a__and^#(mark(X1), X2), mark^#(X1))
, 3: mark^#(add(X1, X2)) -> c_2(a__add^#(mark(X1), X2), mark^#(X1))
, 4: mark^#(first(X1, X2)) -> c_3(mark^#(X1), mark^#(X2))
, 5: mark^#(if(X1, X2, X3)) ->
c_5(a__if^#(mark(X1), X2, X3), mark^#(X1))
, 6: a__add^#(0(), X) -> c_6(mark^#(X))
, 7: a__if^#(true(), X, Y) -> c_7(mark^#(X))
, 8: a__if^#(false(), X, Y) -> c_8(mark^#(Y)) }
Processor 'matrix interpretation of dimension 1' induces the
complexity certificate YES(?,O(n^1)) on application of dependency
pairs {1,2,3,4,5}. These cover all (indirect) predecessors of
dependency pairs {1,2,3,4,5,6,7,8}, their number of application is
equally bounded. The dependency pairs are shifted into the weak
component.
We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).

Obligation:

Answer:
YES(O(1),O(1))
No rule is usable, rules are removed from the input problem.
We are left with following problem, upon which TcT provides the
certificate YES(O(1),O(1)).
Rules: Empty
Obligation:
innermost runtime complexity
Answer:
YES(O(1),O(1))
Empty rules are trivially bounded
Hurray, we answered YES(O(1),O(n^1))
